Form submits to data base and i am trying to stop it when there is an error


Recommended Posts

I have a form and whenever I am entering a invalid email it still goes through.


I have the form set where if it isn't valid it will pop up an error... BUT when I put in the php section it is this.


if (isset($_REQUEST['Submit'])) {











$_POST['fullname']!="" ||

$_POST['blemail']!="" ||

$_POST['comabout']!="" ||

$_POST['prequirements']!="" ||

$_POST['pagenum']!="" ||

$_POST['blemail']==preg_match('/\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i', $_POST['blemail']))



$query="INSERT INTO quote (full_name, company_name, website, email, company_about, project_requirements, page_numbers)VALUES('".$FName."', '".$CName."', '".$Cwebsite."', '".$Email."', '".$comabout."', '".$prequirements."', '".$pagenumber."')";

mysql_query($query) or die("Error updating database.". mysql_error());






table name is quote and it is inserting fine. I just want to stop it if it does not meet any of the following. I can just submit the form blank (except for the pages because it is a dropdown option with one preselected. ) I want to stop the form if a required field is blank OR the email doesn't match the reg ex

The way you have it, the code checks if a field is NOT empty, try reversing it so it checks if any field IS empty:-

// Code to check for empty input boxes (edit to suit your form)
if (empty($email) || empty($name) || empty($subject) || empty($component) || empty($size)) {
echo "Please complete all boxes";
else .........


Separate the email check into a separate if statement.


It's often best to download a form script that has many security features.

http://pastebin.com/SpDarS8J is my exact code. I don't see any non closed if statements. there is an if within an if though.

Can you point out which two lines have the closing "}" for the two if statements?


You need


if ($_POST) {
   ... your code...

       $FName!="" &&
       $Email!="" &&
       $comabout!="" &&
       $prequirements!="" &&
       $Email==preg_match("/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i", $Email)
   ) {

   ... more code

   } // closing bracket
} // closing bracket
