  • PHP MySQL query help

    - by user547794
    Hello, I am trying to use this query to return every instance where the variable $d['userID'] is equal to the User ID in a separate table, and then echo the username tied to that user ID. Here's what I have so far: $uid = $d['userID']; $result = mysql_query("SELECT u.username FROM users u LEFT JOIN comments c ON c.userID = u.id WHERE u.id = $uid;")$row = mysql_fetch_assoc($result); echo $row['username'];

  • Signs that a SQL statement is dangerous

    - by Matt
    Hi, I want to develop a function in PHP that checks how dangerous a SQL statement is. When i say dangerous i mean, certain symbols, characters or strings that are used to get data from a database that the user shouldnt see. For example: SELECT * FROM users WHERE userId = '1' can be injected in several ways. Although i clean the params, i also want to monitor how safe the query is to run. Thanks in advance

  • Maximum number of cookies allowed

    - by Nouveau
    As far as Google searches tell me, the maximum allowed number of cookies depends very much on the browser, however I cannot find any recent data as to how much cookies are allowed on modern browsers. I need to store a somewhat large number of user preferences in cookies (for not-yet-registered users), so what would be the best way of doing that? (Also, those cookies would be accessed both via javascript client-side and php server-side)

  • jquery ajaxSubmit jquery file tree

    Hi, I'm using a jquery file tree and I'd like to allow users to upload files to whatever directory they're currently in. I am having an issue binding the form within the tree, though, since the tree is loading dynamically and obviously can't bind a form that doesn't exist. Any ideas would be greatly appreciated!

  • Implementing OpenID

    - by openid
    Following this tuto: http://www.plaxo.com/api/openid_recipe One of the steps is: Need to look up whether the OpenID entered already belongs to an existing user on your site My problem: what's the OpenID like for a gmail account(I've no other OP account yet)? It seems to me that OpenID = https://www.google.com/accounts/o8/id for gmail, but how can I use that to look up since it's the same for all users?

    - by skynate
    I email out daily sales reports via SQL Server Reporting Services. However, a few users receive on iPhones and the reports don't reload when a new one comes in. It thinks it is the same file as the previous day's report. Is there a way to clear the cache or force a reload?

  • Getting screen height before first display?

    - by Mark
    Hi, I have a ListView. I populate it with 8 items, that's all that fits vertically on the G1. Some of my users are saying the Droid has a taller screen height, and so I can probably add one or two more items to the ListView to take up the additional space provided. How could I measure the available height the screen offers at startup, before the UI is displayed? If I see the height can fit more than 8 items, I'd like to add one or two more rows, Thanks

  • What gems/plugins can be used for Unsubscribe support in Rails?

    - by user550575
    What gems/plugins that make it easy to add a tamper-resistant unsubscribe link to the bottom of the email a user can click to prevent receiving email those types of emails? The only thing I could find was http://kevinlochner.com/handling-unsubscribe-requests-in-ruby-on-rail which works but is somewhat unsophisticated and lacks features such as which type of emails to unsubscribe from. It also doesnt include the mechanism for users to unsubscribe. We using ActionMailer.

  • Camping: Return user to recent entries, but keep errors

    - by echoback
    Users can view a specific entry in my webapp with a URL. /entry/8, for example. If an entry doesn't exist, "Entry not found" gets appended to @messages and I render an error page. I'd like to redirect the user to /recent, but I can't figure out a good way to keep the error message around to be displayed. There are other actions that need to take place in the Recent controller, so I can't just duplicate the query and render :posts.
