  • How should I solve this MySql problem (PHP) ? (Beginner)

    - by Camran
    I have several tables in a MySql database. I have a classifieds website, and at the bottom I display the users last visited classifieds. I do this by storing the ID:s of the ads to an array in the cookie. Now, my db is made up like this kindof: Main Table: // Stores global information, ie these fields have to be filled out in every record, never be blank ID Price category Seller Item Table: // Stores descriptive info about whats for sale ID AD_ID (FK) //This is the same as ID in the MAIN TABLE Color Size Mileage etc My problem is that I need to know what category the ad is in, in order to query mysql for the right information I think. So I need two variables, but the cookie only has one (ID) stored. Offcourse I could make two queries, first one just matching the ID to the main_table and fetch the category from the Main_table. Then make the second query and fetch all other info from the right table. Here is an example if the category was Vehicles: SELECT * FROM main_table, vehicles_table, WHERE main_table.id=$id_from_cookie AND main_table.ad_id=vehicles_table.ad_id As you can see above, I need the category to write in what table to check, right? But I think there must be a smarter way, like fetching them in one single query using only one variable (id from cookie)? How should I do this? Understand? Let me know if you need more input... Thanks

  • Embedding script with timeout in case server goes down

    - by vsync
    I need a way to make sure my script won't block the viewed page, if the server serving the script is down (port 80 is blocked for some reason). Currently when I test it and take down the server (Apache), or close the firewall, I see in the browser that it is trying to load the resource (script in that case), without success for long seconds, until it aborts. Is there a nice way to get past this issue?

  • Problem keeping CSS footer on bottom

    - by Joshy Poshie
    Hey, I'm having trouble with a relative positioned footer. I'm using a clearfooter div to keep the footer at the bottom of each of my pages. This works fine for all resolutions except for 1440x900, any ideas why this resolution would make the header raise up 10 or so pixels off the bottom? CODE: http://pastie.org/929802

  • Make div expand only horizontally when more floating divs are added to it

    - by Wesam
    I am trying to make a div that contains other floating divs to adjust its width such that adding more floating divs (dynamically using jQuery) will only expand the div in its width, not allowing the floating divs to create a new line. Therefore, I want to fix this issue such that each div with class grid-row only expands in width, and so I will be able to scroll using the overflow: scroll for the parent grid div. I have searched a lot for answers, and it seems that it is a famous issue. However, non of the answer solved my problem. I am currently doing this: <div id="grid_container"> <div id="grid"> <div class="grid_row"> <div class="module" id="experience"> Experience </div> <div class="header"> Google </div> <div class="header"> Microsoft </div> </div> <div class="grid_row"> </div> </div> </div> CSS: body { } #grid_container { margin: 50px auto; width: 500px; height: 500px; padding: 10px; border: black solid 1px; } #grid { overflow:scroll; height: 100%; } .grid_row { clear: both; height: 50px; } .module, .header{ padding: 10px; float: left; border: gray solid 1px; }

  • Internet Explorer 8 doesn't finish downloading the page!

    - by Eric the Red
    I'm currently finishing up testing a new Ruby on Rails app. Just recently, some of the pages do not seem to finish downloading in IE8. In FireFox, Chrome and Safari, everything works perfectly. The pages all validate successfully using the W3C validator. When I view the page source in IE8, the page has been chopped off around 75% of the size it should be. IE8 claims the page is finished loading, and doesn't give any errors, but of course the page isn't rendering properly. Has anyone seen this before? I'd really appreciate any help.

  • Within headers, images with alt text vs. text

    - by Court
    Do search engines treat the alt text of an image placed within an h1 tag the same way they would treat regular text placed in an h1 tag? I gave a search through here looking for an answer to this question, but was only able to find information on image replacement and the infamous h1 debate. For example would: <h1><img src="#" alt="Contact Us" /></h1> Act the same as: <h1>Contact Us</h1> In the electronic eye of a search engine? This seems considerably less "CSS Hacky" than other image replacement techniques like negative text indents, display:none, height:0, or ridiculous z-index integers.

  • Why isn't this message subject encoded properly? (php mail)

    - by Camran
    I use this code to send an email: $headers="MIME-Version: 1.0"."\n"; $headers.="Content-type: text/plain; charset=UTF-8"."\n"; $headers.="From: $name <$email>"."\n"; mail($to, '=?UTF-8?B?'.base64_encode($subject).'?=', $text, $headers, '[email protected]'); If I use special characters Å Ä Ö from the swedish alphabet, they are not encoded properly, so they turn up like ö for ö. However, this doesn't happen if I change the $to variable to a gmail account email, then they are shown correctly. Anybody got any idea? Thanks UPDATE: When I echo $name, the name is displayed correctly, in utf8, with all special chars nicely shown.
