    in PHP
    arushibafna-

    Could you give the specific code of your html form you are using or something similar so people can better answer you question?

    For now I can give you this

    If you submit a form you have to set a method. POST, or GET. Also please look at this reference on PHP predefined variables http://www.php.net/manual/en/reserved.variables.php

    Code:
    <form action="submitmarks.php"

      I have to agree with the previous posts that the code you posted is invalid. All of your input tags contain id attributes with "cv", and ids should be unique. Each variable must be given a unique name as well I think but I don't know the full extent of your project.

      Here is an example using getElementsByNa me
      Code:
      var cvTags   = document.getElementsByName("cv");
var cvCount = cvTags.length;

        replied to how to create a round checkbox
        in HTML CSS
        Using CSS alone to change the appearance of a checkbox I would say is "difficult" . Since styling of form elements is browser specific there is no way I know of currently to change all checkbox styles across all browsers. There may be browser specific css extensions, however, I have not been able to find any (at least for Firefox). The closest thing I came across was -moz-appearance: radio; however, you don't get the "tick" that...

          Amzul,

          There are many solutions to your issue, and it really depends on how technical you want to get. I don't have the all the information, but I will make a couple of assumptions.

          1) You want a 2 column layout, a column on the left, and on the right.
          2) You want to keep the width of <div class="line"></div> 400px wide.
          3) You don't want to change your html, only css.

              Security of PHP Superglobals

              Hi everyone,

              I have a question regarding vulnerabilities related to PHP superglobals, in particular $_SERVER.

              I will have a website on a shared hosting environment, and I am unsure of the risks of using the variables such as $_SERVER['DOCUMENT_ROOT'] for things such as "including" files i.e using the include, or require function.

              Are there any know methods to spoof these variables?

                  Yes HTTP_SESSION_VA RS is deprecated. Same thing though.

                  session_registe r() is a deprecated way of registering new session variables. Just use $_SESSION superglobal for all your session needs.

                  1. Make sure you allow cookies on your browser when you are testing your script. If the session cookie is not stored properly on your side then the session_start will always bring up a new session.

                  2. While you are testing...

                    Good idea, Thanks man.

                    Now this question has turned into a MYSQL question.

                    Is it possible to do some simple data integrity checks using queries? For example checking to see if a particular column has only alphanumeric characters in its data, or something like that....

                      ^_^ you do need to session_start() on top of every page. You would think that this would restart a new session, but it doesn't. Basically PHP will do all the background work to see if the user has a cookie (if you are using that method) that has a php session id that matches a session that is currently being stored. If there is a match then all your session variables are stored in the $_SESSION super global

                      hopefully this is the an...

                        I don't see anything wrong with the code you posted that would affect your $_SESSION['user_id'] variable. I would do the following to check to see if the session is being properly stored.

                        1. echo the $_SESSION['user_id'] in the first and second page.
                        2. echo the session_id() to make sure that they are the same.
                        3. If the session id is not the same then for some reason a new session is being created somewhere.

                              I've been creating a login script as well. And actually I finished it in firefox, and it worked fine with safari, and opera, but not IE.

                              It would be great if someone were to post the solution to this.

                              This particular error also comes up in Zend Studio when doing a debug session.

                              IE strikes again -_-

Though vulnerabilities are know, these I believe are related to finding collisions and not actual decryption. People are being recommended to go with the SHA2 variants now.

                                      Well think about it. If you refresh the page what will happen? There is no post data or data to enter into the database, so nothing will happen. The only way a person can submit data is by pressing the submit button. Why don't you try it first.

                                      Also if you are worried about empty entries or invalid entries in your database then you HAVE TO validate your data as I explained in the very first example.
