php form, send email only if all conditions met

[azukah]

hi-

I have this form that works fine: if an image is not the right format or it's too big, it tells the user the error msg and redirects them back to the form BUT it still sends the email... how do i go about sending the email ONLY if the image is the right format & it's within the size limit..???

 

<?php
define ("MAX_SIZE","100"); 
function getExtension($str) {
         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
}
$errors=0;

if(isset($_POST['Submit'])) 
{
	$image=$_FILES['image']['name'];
	if ($image) 
	{
		$filename = stripslashes($_FILES['image']['name']);
  		$extension = getExtension($filename);
		$extension = strtolower($extension);
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
		{
			$error = "<p>Sorry... only jpg, jpeg, gif and png formats are accepted!</p><p><a href='postRequest.php'>Please try again!</a></p>";
		}
		else
		{
$size=filesize($_FILES['image']['tmp_name']);

if ($size > MAX_SIZE*1024)
{
$error = "<p>Sorry... You have exceeded the image size limit!</p><p><a href='postRequest.php'>Please try again!</a></p>";
$errors=1;
}

$image_name=time().'.'.$extension;
$newname="images_board/".$image_name;
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied) 
{
$error = "<p>Sorry... there has been an upload error.</p><p><a href='postRequest.php'>Please try again!</a></p>";
$errors=1;
}}}}
if(isset($_POST['Submit']) && !$errors) 
{
	$error = "<p>Thank You!</p><p>Your request has been submitted</p>";
}
//for email... ///
$studentName=$_POST['studentName'];
$studentId=$_POST['studentId'];
$studentEmail=$_POST['studentEmail'];
$studentPhone=$_POST['studentPhone'];
$postSubject=$_POST['postSubject'];
$postDescription=$_POST['postDescription'];

Wrap your mail logic in an if statement that checks to see if the $error variable is set?

 

Right now your code checks these things, and adds to the error value...but at the bottom of the page that mail logic isn't wrapped in a conditional.

i think i solved it .... i submitted a couple of times with big images and i haven't received any emails..

 

[code=php:0]
<?php
define ("MAX_SIZE","100"); 
function getExtension($str) {
         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
}
$errors=0;

if(isset($_POST['Submit'])) 
{
    $image=$_FILES['image']['name'];
    if ($image) 
    {
       $filename = stripslashes($_FILES['image']['name']);
        $extension = getExtension($filename);
       $extension = strtolower($extension);
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
       {
          $errors=1; // added here
          $error = "<p>Sorry... only jpg, jpeg, gif and png formats are accepted!</p><p><a href='postRequest.php'>Please try again!</a></p>";
       }
       else
       {
$size=filesize($_FILES['image']['tmp_name']);

if ($size > MAX_SIZE*1024)
{
   $errors=1; // moved it here
   $error = "<p>Sorry... You have exceeded the image size limit!</p><p><a href='postRequest.php'>Please try again!</a></p>";
}

$image_name=time().'.'.$extension;
$newname="images_board/".$image_name;
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied) 
{
   $errors=1; // moved it here
   $error = "<p>Sorry... there has been an upload error.</p><p><a href='postRequest.php'>Please try again!</a></p>";
}}}}
if(isset($_POST['Submit']) && !$errors) 
{
    $error = "<p>Thank You!</p><p>Your request has been submitted</p>";
}
//for email... ///

You don't need the $errors anymore, this should do it:

 

<?php
define ("MAX_SIZE","100"); 
function getExtension($str) 
{
$i = strrpos($str,".");
    if (!$i) 
    { 
return ""; 
     }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}

if(isset($_POST['Submit'])) 
{
   $image=$_FILES['image']['name'];

    if($image) 
    {
       	$filename = stripslashes($_FILES['image']['name']);
        $extension = getExtension($filename);
       	$extension = strtolower($extension);

	if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
       	{
                $error = "<p>Sorry... only jpg, jpeg, gif and png formats are accepted!</p><p><a href='postRequest.php'>Please try again!</a></p>";
       	}
       	else
       	{
		$size=filesize($_FILES['image']['tmp_name']);

	if ($size > MAX_SIZE*1024)
	{
   			$error = "<p>Sorry... You have exceeded the image size limit!</p><p><a href='postRequest.php'>Please try again!</a></p>";
	}
	else
	{
		$image_name=time().'.'.$extension;
		$newname="images_board/".$image_name;
		$copied = copy($_FILES['image']['tmp_name'], $newname);

		if (!$copied) 
		{
   				$error = "<p>Sorry... there has been an upload error.</p><p><a href='postRequest.php'>Please try again!</a></p>";
		}
		else
		{
			$error = "<p>Thank You!</p><p>Your request has been submitted</p>";
			//for email... ///
			$studentName=$_POST['studentName'];
			$studentId=$_POST['studentId'];
			$studentEmail=$_POST['studentEmail'];
			$studentPhone=$_POST['studentPhone'];
			$postSubject=$_POST['postSubject'];
			$postDescription=$_POST['postDescription'];

			$to='email@email.com';
			$subject="Bulletin Board Request: $postSubject"; 
			$mainbody.="Student Name: $studentName<br/><br/>";
			$mainbody.="Student Id: $studentId<br><br/>";
			$mainbody.="Contact email: $studentEmail<br/><br/>";
			$mainbody.="Contact Phone: $studentPhone<br/><br/>";
			$mainbody.="Subject: $postSubject<br/><br/>";
			$mainbody.="Description: $postDescription<br/><br/>";
			$mainbody.="Image: $newname<br/>";

			$headers="MIME-Version: 1.0\r\n";
			$headers.="Content-type:text/html;charset=utf-8\r\n"; 
			$headers.="From: $studentName";

			mail($to,$subject,$mainbody,$headers);
		}
	}
}
}
}
?>
