submit form automatically only once

I have made a form which I need to self submit automatically when page is opened. I have tried this javascript code but what it does it creates a loop where form is submitted unlimited time without stop. I need the code where form would be submitted only once when page is opened. Please give me an advice.

<form id="form" action="form.php" method="POST" >
  <select id="main" name="main">
    <option value="1" <?php if (@$_POST['main']=='1') {echo "selected='selected'"; } ?>>One</option>
    <option value="2" <?php if (@$_POST['main']=='2') {echo "selected='selected'"; } ?>>Two</option>
  </select>
</form>

<script>
  document.getElementById("form").submit();
</script>

Below is the java script for submit form automatically you have to import jquery.min.js from http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js

after reading a td value of class error

$("td.error").each(function () {
    // 'this' is now the raw td DOM element
    var txt = $(this).html();
    n=txt.length;   
});
if(n!=0)
    {
        alert(n)
    }
    if(n==0)
    {

        document.forms["login"].submit();
    }

my html file contain code like

<td colspan="2" class="error"><br/><i18n:text><xsl:value-of select="$message"/></i18n:text></td>

you can try onload event in body tag..

like <body onload="submitForm();">

and your function like

<script>
function submitForm()
{
   document.getElementById("form").submit();
}
</script>

You can check if the form was previously submitted with the POST superglobal

<form id="form" action="form.php" method="POST" >
  <select id="main" name="main">
    <option value="1" <?php if (@$_POST['main']=='1') {echo "selected='selected'"; } ?>>One</option>
    <option value="2" <?php if (@$_POST['main']=='2') {echo "selected='selected'"; } ?>>Two</option>
  </select>
</form>

<?php
    if ( ! isset($_POST['main']) ) { // not submitted yet
?>
   <script>
      document.getElementById("form").submit();
   </script>
<?php
    }
?>

try calling on onload of document:

function submitForm()
{
   document.getElementById("form").submit();
}
window.onload=submitForm;

Since page onload called only once when page is completely loaded so it will call it once. Until you are reloading page again by code or using refresh of browser.
