    [HTML] submit form on page load (Not working)

    Hello,

    I was experimenting with javascript and forms to see if i can submit values to a php file on form load. This is what i made so far:

    PHP Code:
    <html>
    <
    head>
    <
    title>Test</title>
    <
    script language="javascript">
    function 
    MyFormSubmit(){
    document.form.submit
    }
    </script>
    </head>
    <body onload="MyFormSubmit()">
    <FORM ACTION="http://localhost/test.php" METHOD="POST">
    <INPUT TYPE="HIDDEN" NAME="username" VALUE="latheesan">FORM>
    </body>
    </html> 
    when i load opened the this page (test.html), it was suppose to post the value "latheesan" to the php script "test.php" file. But it didnt. If it did successfully posted that value, my php file wud say, "you name is latheesan"

    how comes this inst working?

    is some of that code missing where is the submit button? Have you thought of just using pure php so you have a html form and then you do a

    if ($HTTP_POST_VARS['submit']) {

    type tag

    what are you trying to do with the form contents?

    i know this method:

    if ($HTTP_POST_VARS['submit']) {

    but what i wanted to know is a method of auto-submit hidden values that is found on the html form to a php file, when the html file loads.

    Arrow

    Two things,

    HTML mistakes
    You will go into an infinite loop (will just keep submitting):

    PHP Code:
    <html>
    <head>
    <title>Test</title>
    <?php
    if($_POST['username'] == NULL){?>
    <script language="javascript">
    function MyFormSubmit(){
    document.myname.submit();
    }
    </script>
    <?php ?>
    </head>
    <body onload="MyFormSubmit()">
    <FORM ACTION="http://localhost/test.php" METHOD="POST" name="myname" id="myname">
    <INPUT TYPE="HIDDEN" NAME="username" id="username" VALUE="latheesan"> </FORM>
    </body>
    </html>
    Peace,

    I've tried it like this:

    PHP Code:
    <?php

    $list
    ["david"] = "221";
    $list["smith"] = "179";
    $list["cleos"] = "879";

    $i 0;
    while (
    $i 1)
    {
            foreach(
    $list as $user => $id)
            {
                    if((
    $_POST['user'] == NULL) && ($_POST['id'] == NULL))
                    {
                            echo 
    "<script language=\"javascript\">
                                 function MyFormSubmit()
                                 {
                                 document.top.submit();
                                 }
                                 </script>"
    ;
                    }
                    echo 
    "<body onload=\"MyFormSubmit()\">
                         <form action=\"test.php\" method=\"POST\" name=\"top\" id=\"top\">
                         <input type=\"hidden\" name=\"user\" id=\"user\" value=\"
    $user\">
                         <input type=\"hidden\" name=\"id\" id=\"id\" value=\"
    $id\">
                         </form>
                         </body>"
    ;

    I have to understand what you want to do?

    You cant have more than 1 body tags on the same page, well at least you shouldnt?

    You don't need the while(), and your loop will never print the form along with the javascript. Just look at the source of your script (view source in the browser).
    In order to understand recursion, one must first understand recursion.
