[RESOLVED] Facing problems with $_POST in PHP. Data can not be processed by PHP...

sufian

I am new to the world of PHP. Below is my simple PHP file "invite.php" with a form having an image send button (I have to use the image send button because it is the requirement, may be this is causing problem!):

<html>
 <head><title>Form</title>
 </head>
 <body>
  <script language="javascript" src="validation.js"></script>
   <form action="submit.php" method="POST"> 
    <table border ="0" align="center" cellpadding="9" cellspacing="1">          

     <tr>
      <td colspan="2">Enter Your Friends' E-mail Addresses<br/>Separate multiple addresses with a comma<br/>
       <textarea name="emails" id="emails" class="subheading" value="" rows="5" cols="52" onfocus= "javascript:if (document.getElementById('emails').value=='') { document.getElementById('emails').value=''; }" onblur="javascript:if (document.getElementById('emails').value=='') { document.getElementById('emails').value=''; }"></textarea>
      </td>
     </tr>
     <tr>
      <td>Meeting Date<br/>
       <input type="text" name="inputDate" id="inputDate" class="subheading" value="" maxlength="17" size="32" onfocus= "javascript:if (document.getElementById('inputDate').value=='') { document.getElementById('inputDate').value=''; }" onblur="javascript:if (document.getElementById('inputDate').value=='') { document.getElementById('inputDate').value=''; }" />&nbsp;<img src="calendar.gif" alt="Calendar" name="calendar" width="14" height="14" id="calendar" />
      </td>                                                                        

      <td>Meeting Time<br/>
       <input type="text" name="meettime" id="meettime" class="subheading" value=" Noon to Midnight" maxlength="36" size="36" onfocus= "javascript:if (document.getElementById('meettime').value==' Noon to Midnight') { document.getElementById('meettime').value=''; }" onblur="javascript:if (document.getElementById('meettime').value=='') { document.getElementById('meettime').value=' Noon to Midnight'; }" />
      </td>
     </tr>
     <tr>
      <td>Your Name<br/>
       <input type="text" name="vname" id="vname" class="subheading" value=" Your Name" maxlength="36" size="36" onfocus= "javascript:if (document.getElementById('vname').value==' Your Name') { document.getElementById('vname').value=''; }" onblur="javascript:if (document.getElementById('vname').value=='') { document.getElementById('vname').value=' Your Name'; }" />
      </td>
      <td>Your E-mail Address<br/>
       <input type="text" name="visitormail" id="visitormail" class="subheading" value=" Your E-Mail Address" maxlength="36" size="36" onfocus= "javascript:if (document.getElementById('visitormail').value==' Your E-Mail Address') { document.getElementById('visitormail').value=''; }" onblur="javascript:if (document.getElementById('visitormail').value=='') { document.getElementById('visitormail').value=' Your E-Mail Address'; }" /> 
      </td>
     </tr>
     <tr>
      <td colspan="2">Optional Message<br/>
       <textarea name="message" id="message" class="subheading" value="" rows="5" cols="52" onfocus= "javascript:if (document.getElementById('message').value=='') { document.getElementById('message').value=''; }" onblur="javascript:if (document.getElementById('message').value=='') { document.getElementById('message').value=''; }"></textarea>
        <p align="left"><input type="image" src="send.gif" name="send" alt="Send" value="Send" onclick="fValidateContact(this.form); return false;"  /></p> 
      </td>
     </tr>
    </table>
   </form>
 </body>
</html>

The file mentioned in (action="submit.php") is as under:

<html>
 <head><title>Success Message</title>
 </head>
 <body>
  <?php
$inputDate = $HTTP_POST_VARS['inputDate'];
$meettime = $HTTP_POST_VARS['meettime'];
$visitormail = $_POST['visitormail'];
   ?>   

  <table border ="0" align="center" cellpadding="9">          

    <tr>
     <td align="center"><p align="center">Success! Your Data has been processed by PHP. Details are: <br />
     Your Email address was: <?php echo $visitormail; ?><br />
     Meeting Date was : <?php echo $inputDate ?><br />
     Meeting Time was : <?php echo $meettime ?><br /></p>
     </td>
    </tr>
 </table> 
 </body>
</html>

Finally "validation.js" is as under:

function fValidateContact(form)
{
	if(form.emails.value == '')
	{		
            alert("Please enter Your Friend's Email to proceed."); form.emails.focus();
	}
	else if((form.emails.value.indexOf(".") == -1) || (form.emails.value.indexOf("@") == -1))
	{
         alert("Please enter a valid Friend's Email."); form.emails.focus();
	}		
    else if(form.inputDate.value == '')
     {		
 alert("Please choose Meeting Date from the Calendar."); form.inputDate.focus();
     }
    else if(form.meettime.value == '')
     {
 alert("Please enter Meeting Time to proceed."); form.meettime.focus();
     }
    else if(form.vname.value == '')
	{
alert("Please enter Your Name to proceed."); form.vname.focus();
	}
    else if(form.visitormail.value == '')
	{
 alert("Please enter Email Address to proceed."); form.visitormail.focus();
	}
    else if((form.visitormail.value.indexOf(".") == -1) || (form.visitormail.value.indexOf("@") == -1))
	{
alert("Please enter a valid Email Address."); form.visitormail.focus();
	}
	else
	form.submit(); //May be this is the mistake? But what should I do then?
}

I don't understand why PHP is not processing the data provided especially:
$visitormail = $_POST['visitormail'];
Please help me out. Thanks.

First... try this for submit.php

<?php

print_r ($_POST);

?>

This will show you whether you are receiving POST variables correctly or not.

If this doesn't work out, keep it and remove the validation script to see what happens.

Should work out nicely.

Hi schajee
Thank you for your reply.
I have tried the PHP code provided by you in submit.php file, but its not working indicating that this file could not receive POST variables. No change i.e. the affect is the same on removing Validation script and ofcourse removing the call of the function from Image Buttom. I have tried to give a name and ID to the form but still facing the same problem: When I click the Submit button the submit.php file only displays the text but no data which was inserted on the form of the previous php file (invite.php). If data could not be processed by PHP then how come I send an auto mail reply to the visitor of this form (which is yet another requirement to be fulfilled)? Because the mail function in php takes the recepient email as its first argument.
I have even tried this code in submit.php but still not receiving the POST variables:

PHP Code:
<?php
if (isset($POST['inputDate'])) $inputDate = $POST['inputDate']; else $inputDate = null;
if (isset($POST['meettime'])) $meettime = $POST['meettime']; else $meettime = null;
if (isset($POST['visitormail'])) $visitormail = $POST['visitormail']; else $visitormail = null;
?>

Actually this page would be part of a coffee shop website (www.t2f.biz) made on Word Press and someone who wants to meet his/her friends at the coffee shop at a specified time and date will enter the details here and would get an auto mail reply.

I was able to run this code properly, as is.

Hi schajee and FusionComputers,

With Very Best Regards
