Generating Submit Button with Ajax Not Submitting Form Data

[NGmarlys]

Resolved: I had $_SERVER['REQUEST_METHOD'] != 'post' as lowercase. That has to be capital apparently... It worked as soon as I capitalized it, and that was the only change. I voted you up for you fine chaps who helped. Thanks!I'm generating a submit button after a simple math question with Ajax. The Ajax works fine. I can verify with var_dump/print_r that the $_POST and the $_SESSION data is being passed correctly. The submit button is going in the output div like I would expect.However, when I press the submit button, it reloads the page but it does not trigger a submit. It goes back to the form and the $_POST variable is empty / not set at all.The submit button is in the form tags. Why is it submitting the form but not the data / how do I get it to work?I don't think you need the code to answer the question, but nonetheless, here is a simplified version of the code:\[code\]// In a server request method block on test.php: if( $_SERVER['REQUEST_METHOD'] != 'POST' ){<form id="addUserId" name="addUser" method="post" action="test.php" ><table id="formCreatoraddUserIdTableId" cellpadding="2" cellspacing="2" width="100%" > <tr id="formCreatorRowId0" > <td valign="top" ><font>3 minus 1: </font></td> <td valign="top" ><input type="text" id="validatorId" name="validate" onkeyup="makeAjaxRequest('./ajax/captchaSubmitButtonCheck.php', 'captcha='+encodeURIComponent(document.getElementById('validatorId').value),'captchaOutputDiv', '1');" autocomplete="off" /> </td> </tr> <tr id="formCreatorRowId1" > <td valign="top" ><font></font></td> <td valign="top" > <div id="captchaOutputDiv" ></div> </td> </tr> </table> <input type="hidden" name="refreshPostPrevention" /></form> }else{ print_r( $_POST ); // will be empty } // in an ajax file captchaSubmitButtonCheck.php:<?PHPif( $_SERVER['REQUEST_METHOD'] == 'POST' ){ printr( $_POST ); printr( $_SESSION, 'SESSION' ); if( $_POST['captcha'] == $_SESSION['captcha'] ){ echo '<input type="submit" value="http://stackoverflow.com/questions/8560245/Save" />'; }else{ echo '<font class="red">Your math was wrong. Try again.</font>'; }}?> // the JSfunction makeAjaxRequest(url, params, output, image) { var getdate = new Date(); //Used to prevent caching during ajax call if( image == 1 ){ document.getElementById(output).innerHTML='<img src="http://stackoverflow.com/questions/8560245/images/template/ajax-loader.gif"></img>'; } if(xmlhttp) { xmlhttp.open("POST",url,true); xmlhttp.onreadystatechange = function(){ if (xmlhttp.readyState == 4) { if(xmlhttp.status == 200) { document.getElementById(output).innerHTML=xmlhttp.responseText; //Update the HTML Form element } else { alert("Error during AJAX call. Please try again"); } } } xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xmlhttp.send(params); //Posting txtname to PHP File }}\[/code\]
