  • How do I use price data in one table for a calculation that is stored in another table?

    - by shane
    I'm still leanring PHP/MySQL but have learned quite a bit thanks to codies on StackOverflow. I'm trying to setup a sort of room reservations system using two tables: SETUP: Room price table: Has, prices for a type room a client may want to rent as well as the dates (day of week) they wish to use it. Pricing varies based on day of the week and per room. I've setup a different table for each room type as each room type carries different pricing for each day of the week. So, There is an Alpha room table, Bravo room, etc. Within Alpha table are headers for the days of the week with pricing pre-entered into the rows. Client info table: Has the name, address, date of room use, etc data for the specific client. EXAMPLE: Alpha-room price table: Sun = $100; Mon = $200; Tue=$300 and so on. Bravo-room price table: Sun = $100; Mon = $200; Tue=$300 and so on. Client data table: ClientName; date-of-room-use; address; day_subtotal; grand_total. QUESTION: I'm trying to find PHP code that will: look at the date of room use in the client data table, look up the associated cost for that date in the specific room pricing table, record that unit cost in the day subtotal of the client data table and sum a grand total in the grand total row of the client data table (assuming the room may be used more than one day by the customer). I know there's something to do with join but I'm finding it difficult to grasp the concept and, if someone can demonstrate using this example, I think I will have a better understanding of how to work this sort of transaction. Thank you ALL in advance for your suggestions or alternatvie approaches.

  • Stack Overflow like Watermarks in Forms

    - by Kaushik Gopal
    Hey people, I remember seeing a tutorial somewhere that talks of how to style your input forms in a more "usable" way. Essentially, you have a placeholder value and when you enter the input, it hides the hint so to speak. Now, just to be clear: I don't want the hint (placeholder value text) to disappear onFocus, but rather to go lighter when I first start typing something. Good e.gs: Check out the forms on Aardvark http://vark.com/. This is exactly how I wish to have my input forms. Our very own stackoverflow. When you try to ask a question, on clicking inside any input form, it doesn't hide the text right away. You see your cursor as well as the hint. but when you start to type, it hides the hint(I would prefer having it go to a much lighter shade rather than hiding all together, like above example). I remember very clearly reading a tutorial somewhere on the interwebz with this exact requirement, but darn forgot to bookmark it. Any suggestions/links?

  • Bottom of page gets cut off in Safari

    - by VUELA
    I can't figure out why this page: http://wohf.squarespace.com/newsletter/ gets cut off at the bottom in safari, seems to work fine in all other browsers (as far as I found so far)!! I am using some jquery and css for the sidebar and the content to match heights and for the canvas to run top to bottom with the footer always at the very bottom of the page. everything is working (as far as I can tell so far) on the rest of the site, the problem is only on this newsletter page and only in safari. Can anyone see the problem?

  • Question regarding checking the state of a checkbox class

    - by Joseph
    I'll try and make this question simple. Can I assign a class to a series of different checkboxes, and use Jquery to do something when any one of those checkboxes is checked? Searching around on the internet I have found documentation on grabbing the name: $('input[name=foo]').is(':checked') but when I swap out the name attribute for the class attr, it won't work! How can I set an event to occur if any of the checkboxes with this certain class is checked? Please help me out! Thanks

  • Are fluid websites worth making anymore?

    - by Adam
    Hey guys, I'm making a website now and I am trying to decide if I should make it fluid or not. Fixed width websites are much easier to make and also much easier to make them appear consistent. To be honest though, I personally prefer looking at fluid websites that stretch to the full width of my monitor. My question comes from the fact that in most modern browsers you can hold control and scroll your mouse wheel to basically resize any website. So is creating a fluid website worth the trouble?

  • Using CSS to insert text

    - by abelenky
    I'm relatively new to CSS, and have used it to change the style and formatting of text. I would now like to use it to insert text as shown below: <span class="OwnerJoe">reconcile all entries</span> Which I hope I could get to show as: Joe's Task: reconcile all entries That is, simply by virtue of being of class "Owner Joe", I want the text Joe's Task: to be displayed. I could do it with code like: <span class="OwnerJoe">Joe's Task:</span> reconcile all entries. But that seems awfully redundant to both specify the class and the text. Is it possible to do what I'm looking for? EDIT One idea is to try to set it up as a ListItem <li> where the "bullet" is the text "Joe's Task". I see examples of how to set various bullet-styles and even images for bullets. Is it possible to use a small block of text for the list-bullet?

  • PHP Login, Store Session Variables.

    - by Andreas Carlbom
    Yo. I'm trying to make a simple login system in PHP and my problem is this: I don't really understand sessions. Now, when I log a user in, I run session_register("user"); but I don't really understand what I'm up to. Does that session variable contain any identifiable information, so that I for example can get it out via $_SESSION["user"] or will I have to store the username in a separate variable? Thanks.

  • Dojo slider: update value dynamically

    - by xApple
    I am building an application where the user browses certain objects by scrolling and zooming. To change the zoom level I have successfully implemented a "dijit.form.HorizontalSlider" object. Every time the user changes the position of the silder, I can catch the "onChange" call and do something with that. However, the user can also zoom-in by double clicking inside the view zone, at which point the slider should change position automatically to reflect the new zoom level. My question is the following: what function or method should I call in my javascript to update the position of a dojo silder ? Here is the code that creates the silder object: var zoomSlider = new dijit.form.HorizontalSlider({ name: "zoom_slider", id: "zoom_slider", value: 0, minimum: 0, maximum: 19, discreteValues: 20, intermediateChanges: false, style: "width: 160px;", onChange: function(value) { brwsr.view.zoomTo(value); } }, "zoom_slider"); navbox_silder.appendChild(zoomSlider.domNode);

  • Dynamically changing background color of specific text without changing other attributes

    - by gsingh2011
    I've written a chrome extension to find text on a page based on a regex query. When text is matched, I wrap the matched text in a <span> tag that has the class highlight where highlight only changes the background color to yellow. The issue is that sometimes there are already styles applied to <span> tags in a webpage. For example, the webpage might have this defined: span { font-size: 200%; } So when I insert my <span> tag in another <span> tag, the font-size is actually 400%. Is there an easy way for my code to just change certain properties of the text, like the background color, without applying the webpage's styles twice?
