• jQuery ajax in DotNetNuke preserving user authentication

  - by Michael Bradley

  I want to use jQuery's ajax functionality in a DotNetNuke module I'm developing. I want the ajax call to be authenticated via DNN's membership functionality. I want the ajax response as json. How can I do this? I've looked at IWeb and IWebCF -- it's not clear to me from much Googleing and scanning the forums whether these modules would allow me to create a web service that would accept a simple post request and return json (seems like they want to do it the ASP.NET AJAX way with a generated proxy, I'd prefer to just use jQuery's AJAX call functionality). Seems you can't create a simple webmethod in a DNN module (since they are developed as User Controls (.ascx)). I could deploy an .asmx file with module, but that won't leverage DNN's authentication system. Ideas? I'm currently developing against DNN 4.9.5

• JavaScript To Clear Form Field On Submit Before Form Submission To Perl Script

  - by Russell C.

  We have a very long form that has a number of fields and 2 different submit buttons. When a user clicks the 1st submit button ("Photo Search") the form should POST and our script will do a search for matching photos based on what the user entered in the text input ("photo_search_text") next to the 1st submit button and reload the entire form with matching photos added to the form. Upon clicking the 2nd submit button ("Save Changes") at the end of the form, it should POST and our script should update the database with the information the user entered in the form. Unfortunately the layout of the form makes it impossible to separate it into 2 separate forms. I checked the entire form POST and unfortunately the submitted fields are identical to the perl script processing the form submission no matter which submit button is clicked so the perl script can't differentiate which action to perform based on which submit button is pushed. The only thing I can think of is to update the onclick action of the 2nd submit button so it clears the "photo_search_text" field before the form is submitted and then only perform a photo search if that fields has a value. Based on all this, my question is what does the JavaScript look that could clear out the "photo_search_text" field when someone clicks on the 2nd submit button? Here is what I've tried so far none of which has worked successfully: <input type="submit" name="submit" onclick="document.update-form.photo_search_text.value='';" value="Save Changes"> <input type="submit" name="submit" onsubmit="document.update-form.photo_search_text.value='';" value="Save Changes"> <input type="submit" name="submit" onclick="document.getElementById('photo_search_text')='';" value="Save Changes"> We also use JQuery on the site so if there is a way to do this with jQuery instead of plain JavaScript feel free to provide example code for that instead. Lastly, if there is another way to handle this that I'm not thinking of any and all suggestions would be welcome. Thanks in advance for your help!

• IE8 AJAX GET setRequestHeaders not working unless params provided in URL

  - by bobthabuilda

  I'm trying to create an AJAX request in IE8. var xhr = new ActiveXObject( 'Msxml2.XMLHTTP' ); xhr.open( 'GET', '/ajax/' ); // Required header for Django to detect AJAX request xhr.setRequestHeader( 'X-Requested-With', 'XMLHttpRequest' ); xhr.onreadystatechange = function() { if ( this.readyState == 4 ) console.log(this.responseText); } xhr.send( null ); This works perfectly fine in Firefox, Chrome, Safari. In IE8 however, all of my AJAX test requests work EXCEPT for ones where I'm performing GETs without any query string params (such as the one above). POSTs work without question, and GET requests only work whenever I include query strings in the URL, like this: xhr.open( 'GET', '/ajax/?foo=bar' ) I'm also 110% positive that my server code is handling these requests appropriately, so, this stumps me completely. Does anyone have any clue as to what might be causing this?

• TinyMCE not working in http request xhr ajax generated page

  - by user982853

  So i I have a page that contains links that call an httpRequest. The request calls a php file that grabs data from mysql and pre populates a form which is then returned to the browser/webpage. My problem is that when the page is returned to the browser via the httpRequest/ajax the text area does not display the tinymce editor, it just displays a normal text area. It looks like my request and ajax is working fine the text area just doesn't have the tinycme editor on it. When i don't use ajax it works fine but when i put it in a separate file and call it via ajax it doesn't bring in the tinymce editor. Does anyone know how to fix this problem so that my ajax generated page displays the text area with the tinymce editor. Thank you.

• Javascript callback for multiple ajax calls

  - by Jisaak

  My lack of javascript knowledge is getting me in trouble again. I think this should be a fairly easy problem to fix but I cant figure it out. Situation: I want to make three ajax calls in a click event. Each ajax call does a distinct operation and returns back data that is needed for a final callback. The calls themselves are not dependent on one another, they can all go at the same time, however I would like to have a final callback when all three are complete. $('#button').click(function() { fun1(); fun2(); fun3(); //now do something else when the requests have done their 'sucess' callbacks. }); var fun1= (function() { $.ajax({/*code*/}); }); var fun2 = (function() { $.ajax({/*code*/}); }); var fun3 = (function() { $.ajax({/*code*/}); });

• Extract form variable in AJAX response using jquery

  - by Jake

  All, I have a Jquery ajax request calling out a URL. The ajax response I receive is an HTML form with one hidden variable in it. As soon as my ajax request is successful, I would like to retrieve the value of the hidden variabl. How do I do that? Example: html_response for the AJAX call is : <html><head></head><body><form name="frmValues"><input type="hidden" name="priceValue" value="100"></form></body></html> $.ajax({ type: 'GET', url: "/abc/xyz/getName?id="+101, cache: false, dataType: "html", success: function(html_response) { //Extract form variable "priceValue" from html_response //Alert the variable data. } }); Thanks

• Can I make any ASP.NET/HTML element into form-data that posts back to the server?

  - by Giffyguy

  I am using Javascript to alter the innerHTML attribute of a <td> and I need to get that info back in the form submittal. The <td> corrosponds to an <asp:TableCell> on the server-side, where the Text attribute is set to an initial value. The user cannot enter the value in this particular field. Instead, its value is set by me (via client-side script) based on actions that the user performs. But this field is useless to me if I can't see its value on the server-side as well. I'd like to avoid using a read-only textbox, because those are difficult to resize dynamically. Can an <asp:Label> be used as form data? Is there any way to achive this without letting the user manually enter the data? Or is there a simpler way to store a string as a variable somewhere and send it back as form-data?

• iPad web app: Prevent input focus AFTER ajax call

  - by Mike Barwick

  So I've read around and can't for the life of me figure out of to solve my issue effectively. In short, I have a web app built for the iPad - which works as it should. However, I have an Ajax form which also submits as it should. But, after the callback and I clear/reset my form, the "iPad" automatically focuses on an input and opens the keyboard again. This is far from ideal. I managed to hack my way around it, but it's still not perfect. The code below is run on my ajax callback, which works - except there's still a flash of the keyboard quickly opening and closing. Note, my code won't work unless I use setTimeout. Also, from my understanding, document.activeElement.blur(); only works when there's a click event, so I triggered one via js. IN OTHER WORDS, HOW DO I PREVENT THE KEYBOARD FROM REOPENING AFTER AJAX CALL ON WEB APP? PS: Ajax call works fine and doesn't open the keyboard in Safari on the iPad, just web app mode. Here's my code: hideKeyboard: function () { // iOS web app only, iPad IS_IPAD = navigator.userAgent.match(/iPad/i) != null; if (IS_IPAD) { $(window).one('click', function () { document.activeElement.blur(); }); setTimeout(function () { $(window).trigger('click'); }, 500); } } Maybe it's related to how I'm clearing my forms, so here's that code. Note, all inputs have tabindex="-1" as well. clearForm: function () { // text, textarea, etc $('#campaign-form-wrap > form')[0].reset(); // checkboxes $('input[type="checkbox"]').removeAttr('checked'); $('#campaign-form-wrap > form span.custom.checkbox').removeClass('checked'); // radio inputs $('input[type="radio"]').removeAttr('checked'); $('#campaign-form-wrap > form span.custom.radio').removeClass('checked'); // selects $('form.custom .user-generated-field select').each(function () { var selection = $(this).find('option:first').text(), labelFor = $(this).attr('name'), label = $('[for="' + labelFor + '"]'); label.find('.selection-choice').html(selection); }); optin.hideKeyboard(); }

• ASP.NET AJAX, WebSeal Junctions, and Sessions

  - by powella

  I've run up across a problem with ASP.NET AJAX (hooked up to WebServices directly) and accessing our site through a WebSeal junction. Listing 11. On this page; http://www.ibm.com/developerworks/tivoli/library/t-ajaxtam/index.html explains that requests to pages which do not result in a content type of text/html are not sent with cookie data. Hence, no session. ASP.NET AJAX requests are returned with a content type of "application/json; charset=utf-8". As such, the WebSeal junction is not appending the Session Cookie to the request. This results in our WebService seeing the user as invalid, due to no session information. The Junction has been setup properly with the -J parameter (thats an uppercase J, which appends the required script for WebSeal to the bottom of the page - this prevents forcing IE into quirks mode.) and we've confirmed that the necessary script exists in the output source. I'm up for any suggestions at this point, as I'm out of ideas. FWIW, the site runs perfectly when not accessed through the WebSeal Junction.

• POST Fail via AJAX Request?

  - by Jascha

  I can't for the life of me figure out why this is happening. This is kind of a repost (submitted to stackoverflow, but maybe a server issue?). I am running a javascript log out function called logOut() that has make a jQuery ajax call to a php script... function logOut(){ var data = new Object; data.log_out = true; $.ajax({ type: 'POST', url: 'http://www.mydomain.com/functions.php', data: data, success: function() { alert('done'); } }); } the php function it calls is here: if(isset($_POST['log_out'])){ $query = "INSERT INTO `token_manager` (`ip_address`) VALUES('logOutSuccess')"; $connection->runQuery($query); // <-- my own database class... // omitted code that clears session etc... die(); } Now, 18 hours out of the day this works, but for some reason, every once in a while, the POST data will not trigger my query. (this will last about an hour or so). I figured out the post data is not being set by adding this at the end of my script... $query = "INSERT INTO `token_manager` (`ip_address`) VALUES('POST FAIL')"; $connection->runQuery($query); So, now I know for certain my log out function is being skipped because in my database is the following data: if it were NOT being skipped, my data would show up like this: I know it is being skipped for two reasons, one the die() at the end of my first function, and two, if it were a success a "logOutSuccess" would be registered in the table. Any thoughts? One friend says it's a janky hosting company (hostgator.com). I personally like them because they are cheap and I'm a fan of cpanel. But, if that's the case??? Thanks in advance. -J

• Is this spaghetti code already? [migrated]

  I post the following code writen all by hand. Why I have the feeling that it is a western spaghetti on its own.

• jQuery validation plugin and .ajax

  - by FALCONSEYE

  So, I have a form where I load divs as I go asking for various user input and displaying some offers. I have the following: $("#calcPrice").click(function() { $("#invPricing").validate({ rules: { ... }, messages: {... } , submitHandler: function(form) { .... $.ajax({ }); $.ajax({ }); return false; } }); My problem is after validation, none of the ajax calls work. If I remove the validation methods (rules, messages, submitHandler), everything works fine. Can somebody tell me what I am missing here? thanks in advance. btw, these are the ajax calls: $.ajax({ dataType: "json", type: "get", url: <cfoutput>"#actURL#"</cfoutput>, data: formData+"&p_type=LOW&returnJSON=true", cache: false, success: function(result) { // fields to populate: $("#rent").val(result.RENT); $("#discount").val(result.DISCOUNT); $("#salesPrice1").val(result.SALESPRICE); $("#cashPrice1").val(result.CASHSALESPRICE); $("#tax1").val(result.SALESTAX); $("#payment1").val(result.PAYMENTS); } , error: function(xmlHttpRequest, status, err) { confirm('Error!' + err); } }); $.ajax({ dataType: "json", type: "get", url: <cfoutput>"#actURL#"</cfoutput>, data: formData+"&p_type=HIGH&returnJSON=true", cache: false, success: function(result) { // fields to populate: $("#rent").val(result.RENT); $("#discount").val(result.DISCOUNT); $("#salesPrice2").val(result.SALESPRICE); $("#cashPrice2").val(result.CASHSALESPRICE); $("#tax2").val(result.SALESTAX); $("#payment2").val(result.PAYMENTS); } , error: function(xmlHttpRequest, status, err) { confirm('Error!' + err); } }); I am basically displaying two offers one Low, one High.

• jQuery AJAX call not working in Webkit

  - by Brian

  I've run into a strange issue with Webkit based browsers (both Safari and Chrome - I'm testing on a Mac) and I am not sure what is causing it. Here's a small script I've created that replicates the issue: <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" language="javascript"> function doRequest() { document.test.submit(); $.ajax({ type: "GET", cache: false, url: 'ajax.php?tmp=1', success: doSuccess }); } function doSuccess(t_data,t_status,req) { alert('Data is: '+ t_data +', XMLHTTPRequest status is: '+ req.status); } </script> </head> <body> <form name="test" method="post" action="ajax.html" enctype="multipart/form-data"> <input type="file" name="file_1"> <br><input type="button" value="upload" onclick="doRequest();"> </form> </body> </html> ajax.php is: <?php echo $_REQUEST['tmp']; ?> This works as is on Firefox, but the XMLHTTPRequest status is always "0" on both Safari and Chrome. If I remove this line: document.test.submit(); then it works, but of course the form is not submitted. I've tried changing the form submit button from "button" to "submit", but that also prevents it from working on Safari or Chrome. What I am trying to accomplish is: submit the form call another script to get status on the file being uploaded via the form (it's for a small upload progress meter). Any help is really appreciated - I'm hopeful it is just a quirk I'm not familiar with. Thanks! Brian

• jquery ajax post canceled

  - by hsemu

  I want to track the mouse click events on a set of UI components on a set of pages. To do this, I am using the following jquery/ajax call(trimmed out u): 1.Ajax call which will add the click logging. myClickLogger = { endpoint: '/path/to/my/logging/endpoint.html', logClickEvent: function(clickCode) { $.ajax({ 'type': 'POST', 'url': this.endpoint, 'async': true, 'cache': false, 'global': false, 'data': { 'clickCode':clickCode }, 'error': function(xhr,status,err){ alert("DEBUG: status"+status+" \nError:"+err); }, 'success': function(data){ if(data.status!=200){ alert("Error occured!"); } } }); } }; 2.JQuery click event which will call the ajax logger(the clickCode is an identifier for which button/image was clicked): $(document).ready(function() { $(".myClickEvent[clickName]").click(function() { var clickCode = $(this).attr("clickName"); myClickLogger.logClickEvent(clickCode); }); }); The above ajax call(1.) is "canceled" by browser whenever the button click being tracked takes to a new page. If I change 'aysnc' to 'false', then the ajax call succeeds. Also, click events which do not take to a new page succeed. Only the click events taking to new page are being canceled. I do not want to make the call synchronous. Any ideas, what could be the issue? How can I guarantee that the asynchronous call before is finished when the click event takes to a new page?

• Why does calling abort() on ajax request cause error in ASP.Net MVC (IE8)

  - by user169867

  I use jquery to post to an MVC controller action that returns a table of information. The user of the page triggers this by clicking on various links. In the event the user decides to click a bunch of these links in quick succession I wanted to cancel any previous ajax request that may not have finished. I've found that when I do this (although its fine from the client's POV) I will get errors on the web application saying that "The parameters dictionary contains a null entry for parameter srtCol of non-nullable type 'System.Int32'" Now the ajax post deffinately passes in all the parameters, and if I don't try and cancel the ajax request it works just fine. But if I do cancel the request by calling abort() on the XMLHttpRequest object that ajax() returns before it finishes I get the error from ASP.Net MVC. Example: //Cancel any pevious request if (req) { req.abort(); req = null; } //Make new request req= $.ajax({ type: 'POST', url: "/Myapp/GetTbl", data: {srtCol: srt, view: viewID}, success: OnSuccess, error: OnError, dataType: "html" }); I've noticed this only happen is IE8. In FF it seems to not cuase a problem. Does anyone know how to cancel an ajax request in IE8 without causing errors for MVC? Thanks for any help.

• jQuery ajax call doesn't seem to do anything at all

  - by icemanind

  I am having a problem with making an ajax call in jQuery. Having done this a million times, I know I am missing something really silly here. Here is my javascript code for making the ajax call: function editEmployee(id) { $('#<%= imgNewEmployeeWait.ClientID %>').hide(); $('#divAddNewEmployeeDialog input[type=text]').val(''); $('#divAddNewEmployeeDialog select option:first-child').attr("selected", "selected"); $('#divAddNewEmployeeDialog').dialog('open'); $('#createEditEmployeeId').text(id); var inputEmp = {}; inputEmp.id = id; var jsonInputEmp = JSON.stringify(inputEmp); debugger; alert('Before Ajax Call!'); $.ajax({ type: "POST", url: "Configuration.aspx/GetEmployee", data: jsonInputEmp, contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { alert('success'); }, error: function (msg) { alert('failure'); } }); } Here is my CS code that is trying to be called: [WebMethod] public static string GetEmployee(int id) { var employee = new Employee(id); return Newtonsoft.Json.JsonConvert.SerializeObject(employee, Newtonsoft.Json.Formatting.Indented); } When I try to run this, I do get the alert that says Before Ajax Call!. However, I never get an alert back that says success or an alert that says failure. I did go into my CS code and put a breakpoint on the GetEmployee method. The breakpoint did hit, so I know jQuery is successfully calling the method. I stepped through the method and it executed just fine with no errors. I can only assume the error is happening when the jQuery ajax call is returning from the call. Also, I looked in my event logs just to make sure there wasn't an ASPX error occurring. There is no error in the logs. I also looked at the console. There are no script errors. Anyone have any ideas what I am missing here? `

• web browser become slow or no response after several ajax calls

  - by Patrick

  I'm totally newbie to jquery and ajax, my recently project is to help the representatives (reps) to manage customer quotations online. I have a page which displays all the quotations in a big table. I've managed to use ajax to fetch and display the quotations which associate to a particular rep after i click that rep's name. But the only problem is the speed of response. The first few clicks are ok and very smooth. But after several tries, the response become slow and I cant even scroll down the webpage, and later on the web browser craches.... Please have a look at my ajax code. here it is: <!-- AJAX FETCH QUOTES DATA + Tablesorter + FIXED TABLE HEADER--> <script type="text/javascript"> //<![CDATA[ $(function(){ $("a.repID").click(function(){ $('div#loader').append("<p align='center'><img src='images/loadingbar2.gif' id='loading' /></p>"); var repID = $(this).attr("title"); $.ajax({ type:'POST', url:'quote_info.php', data:'repID=' + repID, cache: false, success:function(data) { $("#container").html('<div id="content">' + data + '</div>'); $("#loading").fadeOut(500, function() {$(this).remove();}); $("#sortme").tablesorter(); $('.tbl').fixedtableheader(); } }); return false; }); }); </script> <!-- AJAX FETCH QUOTES DATA + Tablesorter + FIXED TABLE HEADER-->

• Getting jQuery to return an ajax object

  - by japancheese

  Hello, The question title is a bit strange because I'm not exactly sure how to phrase the problem. The issue is that I have many links to which I want to bind a click event with an ajax call, and I'm just looking to refactor some duplicate code into a single area. The links I'm trying to bind an ajax call only have one thing that differentiates them, and that's an id from a previously declared object. So I have lots of code that looks like this: $("a.link").bind('click', function() { id = obj.id; $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); I was trying to refactor it into something like this: $("a.link").bind('click', ajax_link(obj.id)); function ajax_link(id) { $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); However, as you can imagine, this just actually makes the ajax call when the element is binded with the click event. Is there an easy way to refactor this code so I can extract out the common ajax code into its own function, and hopefully reduce the number of lines of jQuery in my current script?

• jQuery ajax success not work in codeigniter

• Are AJAX sites crawlable by search engines?

  - by frankadelic

  I had always assumed that AJAX-driven content was invisible to search engines. (i.e. content inserted into the DOM via XMLHTTPRequest) For example, in this site, the main content is loaded via AJAX request by the browser: http://www.trustedsource.org/query/terra.cl ...if you view this page with Javascript disabled, the main content area is blank. However, Google cache shows the full content after the AJAX load: http://74.125.155.132/search?q=cache:JqcT6EVDHBoJ:www.trustedsource.org/query/terra.cl+http://www.trustedsource.org/query/terra.cl&cd=1&hl=en&ct=clnk&gl=us So, apparently search engines do index content loaded by AJAX. Questions: Is this a new feature in search engines? Most postings on the web indicate that you have to publish duplicate static HTML content for search engines to find them. Are there any tricks to get an AJAX-driven content to be crawled by search engines (besides creating duplicate static HTML content). Will the AJAX-driven content be indexed if it is loaded from a separate subdomain? How about a separate domain?

Here are the snippets of code that I am trying, and cannot get to work: $.ajax({ type: "POST", url: "http://10.0.2.2:28434/api/devices", data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'} }).always(function( data, textStatus, jqXHR ) { alert( textStatus ); }); Whenever I run this request I always get back a textStatus of 'error'. After hours of trying different things, I pushed my End Point to an actual server, and was able to actually get responses back in PhoneGap if I built up an XMLHttpRequest by hand, like so: var request = new XMLHttpRequest(); request.open("POST", "http://172.16.100.42/MobileRewards/api/devices", true); request.onreadystatechange = function(){//Call a function when the state changes. console.log("state = " + request.readyState); console.log("status = " + request.status); if (request.readyState == 4) { if (request.status == 200 || request.status == 0) { console.log("*" + request.responseText + "*"); } } } request.send("{EncryptedPassword:1234,UserName:test,DeviceToken:d234}"); Unfortunately, if I try to use $.ajax() against the same end point in the snippet above I still get a status text that says 'error', here is that snippet for reference: $.ajax({ type: "POST", url: "http://172.16.100.42/MobileRewards/api/devices", data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'} }).always(function( data, textStatus, jqXHR ) { alert( textStatus ); }); So really, there are a couple of questions here. 1) Why can't I get any ajax calls (post or get) to successfully hit my End Point when it's hosted via IIS Express on the same machine that the Android VM is running? 2) When my end point is hosted on an actual server, through IIS and served through port 80, why can't I get post requests to be successful when I use jquery's ajax calls? (Even though I can get it to work by manually creating an XMLHttpRequest) Thanks

• Form values appear blank when submitting to the database - Drupal FormAPI

  - by GaxZE

  Hello, I have been working on this drupal form API script for past week and half. to give an insight into my problem.. the form below merely lists a host of database records which contain 5 individual scoring ranks. (mind, action, relationship, language and IT). this code is apart of my own custom module where all values are listed from the database. the idea behind this module is to be able to edit these values on a large scale. I am having trouble getting the values entered in the form to be passed to the variables inside of the marli_admin_submit function. the second problem is the assigning those values to their specific ID. for this purpose id like to add im merely trying to get just one score updated rather than all of them. below is my code. any advice appreciated. function marli_scores(){ $result = pager_query(db_rewrite_sql('SELECT * FROM marli WHERE value != " "')); while ($node = db_fetch_object($result)) { $attribute = $node->attribute; $field = $node->field_name; $item = $node->value; $mind = $node->mind; $action = $node->action; $relationship = $node->relationship; $language = $node->language; $it = $node->it; $form['field'][$node->marli_id] = array('#type' => 'markup', '#value' => $field, '#prefix' => '<b>', '#suffix' => '</b>'); $form['title'][$node->marli_id] = array('#type' => 'markup', '#value' => $item, '#prefix' => '<b>', '#suffix' => '</b>'); $form['mind'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $mind); $form['action'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $action); $form['relationship'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $relationship); $form['language'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $language); $form['it'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $it); } $form['pager'] = array('#value' => theme('pager', NULL, 50, 0)); $form['save'] = array('#type' => 'submit', '#value' => t('Save')); $form['#theme'] = 'marli_scores'; return $form; } function marli_admin_submit($form, &$form_state) { $marli_id = 4; $submit_mind = $form_state['values']['mind'][$marli_id]; $submit_action = $form_state['values']['action'][$marli_id]; $submit_relationship = $form_state['values']['relationship'][$marli_id]; $submit_language = $form_state['values']['language'][$marli_id]; $submit_it = $form_state['values']['it'][$marli_id]; $sql_query = "UPDATE {marli} SET mind = %d, action = %d, relationship = %d, language = %d, it = %d WHERE marli_id = %d"; if ($success = db_query($sql_query, $submit_mind, $submit_action, $submit_relationship, $submit_language, $submit_it)) { drupal_set_message(t(' Values have been saved.')); } else { drupal_set_message(t('There was an error saving your data. Please try again.')); } }
