• Unable to return/process JSON in JQuery $.get()

  - by shyam

  I have a problem returning/processing JSON data while calling $.get() function. Here's the code: JQuery: $.get("script.php?", function(data) { if (data.status) { alert('ok'); } else { alert(data.error); } },'json'); PHP if ($r) { $ret = array("status"=>true); } else { $ret = array("status"=>false,"error"=>$error); } echo json_encode( $ret ); So this is the code. But the response is always taken as string in the jquery. data.status and data.error is undefined.

• using jquery $.post() for returning multiple values

  - by Aninemity

  Hi all I am trying to use a $.post() in the following way: $.post("file.php", { file_id: $(this).val()}, function(data){...} The file.php then does a database query and returns an array with a title, description and image reference. What I want to do then is be able to update the .val() for form fields for each. I understand how to do this on a single variable, it would just be the following: $.post("file.php", { file_id: $(this).val()}, function(data){ $('#title').val(data); } But, how do I get the data returned to be recognizable in jquery as either separate variables or as an array? Thanks in advance

• Recursive MySQL function call eats up too much memory and dies.

  - by kylex

  I have the following recursive function which works... up until a point. Then the script asks for more memory once the queries exceed about 100, and when I add more memory, the script typically just dies (I end up with a white screen on my browser). public function returnPArray($parent=0,$depth=0,$orderBy = 'showOrder ASC'){ $query = mysql_query("SELECT *, UNIX_TIMESTAMP(lastDate) AS whenTime FROM these_pages WHERE parent = '".$parent."' AND deleted = 'N' ORDER BY ".$orderBy.""); $rows = mysql_num_rows($query); while($row = mysql_fetch_assoc($query)){ // This uses my class and places the content in an array. MyClass::$_navArray[] = array( 'id' => $row['id'], 'parent' => $row['parent'] ); MyClass::returnPArray($row['id'],($depth+1)); } $i++; } Can anyone help me make this query less resource intensive?

• How do I link to another action in Magento whilst passing a parameter to the controller?

  - by desbest

  I need to pass a parameter, because I would like to redirect back to the module and query string of the current page. So I can get from showdown/index?id=35 --click--- showdown/vote?id=1 showdown/vote?id=1 --redirect-- showdown/index?id=35 The vote action is not seen. (The redirect method doesn't work as it takes the index.php url only and no actions, and I cannot find a helper in Magento for creating hyperlinks.) Does Magneto have a link helper for this? Example of stuff I want: <a href="<?php echo Mage::Helper->Link->($url, $array); ?> then $array or whatever variables gets sent to the controller.

• PHP Math issue with negatives [closed]

  - by user1269625

  Possible Duplicate: PHP negatives keep adding I have this code here.... $remaining = 0; foreach($array as $value=>$row){ $remaining = $remaining + $row['remainingbalance']; } What its doing is that it is going through all the remaining balances in the array which are -51.75 and -17.85 with the code above I get -69.60 which is correct. But I am wondering how when its two negatives if they could subtract? Is that possible? I tried this $remaining = 0; foreach($clientArrayInvoice as $value=>$row){ $remaining = $remaining + abs($row['remainingbalance']); } but it gives me 69.60 without the negative. Anyone got any ideas? my goal is to take -51.75 and -17.85 and come up with -33.90 only when its a negative to do subtract. otherwise add

• How to assign variable dynamically to php list function

  - by ravisoni

  What I am doing that I want to generate a list based on how many items are in an array, so I have counted the items and loop over them, create a number based var and construct a string $var which contains $a1,$a2.... and assigns the $var to list list($var) and tried to access $a1 but it gives me the error "Undefined variable: a1" Is there any other way to do it? Here is my code: $arr = array('1','2','3'); $listsize = count($arr); $var=''; for($i=1;$i<=$listsize;$i++){ $var.='$a'.$i; if($i!=$listsize){ $var.=','; } } list($var) = $arr; echo $a1;

• Hidden field value set with jQuery doesn't submit

  - by Will

  I'm completely perplexed. I set the value of a hidden field with jQuery and the submit the form. The hidden value is present when I dump the $_POST array via PHP unless I use Internet Explorer. Here's the test code: $('#hidden-field').val('I am a hidden value'); // To make sure it's setting properly ... // This shows its being set in FF, Chrome, **AND** IE alert($('#hidden-field').val()); Then on the PHP side: print_r($_POST); For submissions made with IE the result looks like this: Array ( [hidden-field] => ) Other browsers have the value. Help? Why doesn't the value submit and how can I make it?

• Serialize object from within

  - by Maximus

  I have the class testClass which has the method save. This method saves object to a database. But it needs to serialize object before saving. How can I serialize object from within the class to do that? class testClass { private $prop = 777; public function save() { $serializedObject = serialize(self); DB::insert('objects', array('id', 'object')) ->values(array(1, $serializedObject)) ->execute(); } } serialize(self) obviously doesn't work.

My dual (UBUNTU/WINDOWS) Desktop sound works fine in windows. My DELL Inspiration laptop sound works fine in UBUNTU 14.04 LTS. Does anybody know which is actually the origin of the problem? Is there any solution diferent to essay-error methodology? Isn't every newer version of UBUNTU enough double checked before releasing it?

• Get total marker count from Google API placesSearch

  - by okTalk

  In the example fiddle, how can I get the total number of markers displayed on the map? I'm pushing each of the markers into an array like this: markers.push(marker) And attempting to get the total number of markers like this: $('.marker-count span').html(markers.length); Unfortunately, "markers.length" is returning 0 when it should be returning at least 3. I have example code here: http://jsfiddle.net/287C7/ How can I display the total number of markers? Is it not possible to add each marker to my array? I need to know the amount of markers shown so that I can alert the user if there are none. Thanks,

• Why is casting and comparing in PHP faster than is_*?

  - by tstenner

  While optimizing a function in PHP, I changed if(is_array($obj)) foreach($obj as $key=$value { [snip] } else if(is_object($obj)) foreach($obj as $key=$value { [snip] } to if($obj == (array) $obj) foreach($obj as $key=$value { [snip] } else if($obj == (obj) $obj) foreach($obj as $key=$value { [snip] } After learning about ===, I changed that to if($obj === (array) $obj) foreach($obj as $key=$value { [snip] } else if($obj === (obj) $obj) foreach($obj as $key=$value { [snip] } Changing each test from is_* to casting resulted in a major speedup (30%). I understand that === is faster than == as no coercion has to be done, but why is casting the variable so much faster than calling any of the is_*-functions?

• How to get it working in O(n)?

  - by evermean

  I came across an interview task/question that really got me thinking ... so here it goes: You have an array A[N] of N numbers. You have to compose an array Output[N] such that Output[i] will be equal to multiplication of all the elements of A[N] except A[i]. For example Output[0] will be multiplication of A[1] to A[N-1] and Output[1] will be multiplication of A[0] and from A[2] to A[N-1]. Solve it without division operator and in O(n). I really tried to come up with a solution but I always end up with a complexity of O(n^2). Perhaps the is anyone smarter than me who can tell me an algorithm that works in O(n) or at least give me a hint...

• Ruby - overriding/enabling multiple assignment (e.g. `a, b, c = d, e, f`)

  - by nicholaides

  In ruby, you can do this: d = [1, 2, 3] a, b, c = d a, b, and c, will receive the values 1, 2, and 3, respectively. d, in this case in an Array and ruby knows to assign it's contents to a, b, and c. But, if d were a Fixnum, for example, only a would be assigned to the value of d while b and c would be assigned nil. What properties of d allow it to be used for multiple assignment? In my exploring so far, I've only been able to make instances of subclasses of Array behave in this way.

• C#: reading in a text file more 'intelligently'

  - by DarthSheldon

  I have a text file which contains a list of alphabetically organized variables with their variable numbers next to them formatted something like follows: aabcdef 208 abcdefghijk 1191 bcdefga 7 cdefgab 12 defgab 100 efgabcd 999 fgabc 86 gabcdef 9 h 11 ijk 80 ... ... I would like to read each text as a string and keep it's designated id# something like read "aabcdef" and store it into an array at spot 208. The 2 issues I'm running into are: I've never read from file in C#, is there a way to read, say from start of line to whitespace as a string? and then the next string as an int until the end of line? given the nature and size of these files I do not know the highest ID value of each file (not all numbers are used so some files could house a number like 3000, but only actually list 200 variables) So how could I make a flexible way to store these variables when I don't know how big the array/list/stack/etc.. would need to be.
