Check Form Fields Before Email

thesaleboat · August 21, 2008

What I am trying to do is have this form be verified that all of the fields are filled out before it is emailed. But when i test it, it just refreshes the page, and deleted all the stuff typed in, instead of popping up an alert. Does php have a separate way to send alerts?

<form name="resume" action="<?php echo $_SERVER['PHP_SELF'];?>" method="post" >
<div align="center">
<span class="mainHeader2" >Online Resume Submission:</span><br />
<span class="mainTextNoIndent">Please fill out the following form.</span><br/><br/>
<span class="mainTextNoIndent"><strong>Name:</strong></span><br/>
<input type="text" name="requiredName" id="requiredName" value="<?php echo $row['requiredName'];?>" size="20" maxlength="10" /><br/><br/>
<span class="mainTextNoIndent"><strong>Email Address:</strong></span><br/>
<input type="text" name="requiredEmailAddress" id="requiredEmailAddress" value="<?php echo $row['requiredEmailAddress'];?>" size="30" /><br/><br/>
<span class="mainTextNoIndent"><strong>Miscellaneous: </strong></span><br/>
<textarea name="Miscellaneous" id="Miscellaneous" value="<?php echo $row['Miscellaneous'];?>" rows="8" cols="85"></textarea><br/><br/>
<span class="mainTextNoIndent"><strong>* Please ensure your email address is correct before submitting.</strong></span><br/>
<input type="submit" name="submit" value="Submit" /><br/>
</div>
<br/>
</form>
<?php
if (isset($_POST['submit']))
{
// Get Information from form
$Name=$_POST['requiredName'];
$EmailAddress=$_POST['requiredEmailAddress'];
$Miscellaneous=$_POST['Miscellaneous'];

if (empty($Name)) {
$error = 'You did not fill in your email address.';
alert("The first name field is a required field.");
} 
else if (empty($EmailAddress)) {
$error = 'You did not fill in your email address.';
alert("The email address field is a required field.");							
} 
else if (empty($EmailAddress)) {
$error = 'You did not fill in your email address.';
alert("The miscellaneous field is a required field.");
}
if (!$error) {
$EmailAddress = trim($EmailAddress);
$to = "me@behindyou.com";
$subject = "Online Resume Submittion";
$EmailAddress=$_POST['EmailAddress'];
$from = "From: ".$EmailAddress;
$message = "First Name: \n".$Name." ";
$message .= "\n\n\nEmail Address: \n".$EmailAddress." ";
$message .= "\n\n\nMiscellaneous: \n".$Miscellaneous." ";

mail($to, $subject, $message, $from); //Send Email 
echo "Thank you for your application, we will be in contact with you shortly if you meet the job description requirements.";
echo '<meta content="4; URL=index.htm" http-equiv="Refresh" />';//go back to homepage after they read the thank you message
}
}
?>

Where is $row defined?

thesaleboat · August 21, 2008

??? hmm very good point

is there something else i should use for the value? or how would i define $row?

to the best of my knowledge, alert() is not a PHP function. you may be thinking javascript.

for errors, i usually echo them to the page in case javascript is turned off, putting the submitted values into the text fields so they don't have to be filled in again.

example:

$errors = array();
if (trim($_POST['fname']) == "") {
    $errors[] = "First name is required.";
}

if (trim($_POST['lname']) == "") {
    $errors[] = "Last name is required.";
}

if (count($errors) == 0) { 
     // no errors, send emails
} else {
    // there are errors. display them.
    echo "Please correct the following errors:<BR>";
    echo implode('<BR>',$errors);
}

In your form, everywhere where you have...

<?php echo $row['requiredName'];?>

for example needs to be changed to....

<?php echo isset($_POST['requiredName']) ? $_POST['requiredName'] : '';?>

yes sorry that i havent responded in a while guys, been kinda hectic. Alert is javascript, but this is the wierd thing, when i tested it on my XAMP local server the alert would pop up and the form could not be submitted until the user entered all Required fields, but when i put it online no alert would pop up and the form could be submitted empty, any thoughts on that. also blueSkyIS, how do you make the text fields write back to themselves if the 'if' statements arent passed. that is the only reason im trying to have it be action="<?php echo $_SERVER['PHP_SELF'];?>" i had this form working perfectly already. here is my code at this time.

<form name="resume" action="<?php echo $_SERVER['PHP_SELF'];?>" method="post" >

thesaleboat · August 26, 2008

Alright, i took the two suggestions and put them in place, but now when the form is not filled out or the email address is not in proper format it will still be submitted and emailed, please help!

<?php
if (isset($_POST['submit']))
{
// Get Information from form
$FirstName=$_POST['requiredFirstName'];
$MiddleInitial=$_POST['requiredMiddleInitial'];
$LastName=$_POST['requiredLastName'];
$TelephoneNumber=$_POST['requiredTelephoneNumber'];
$EmailAddress=$_POST['requiredEmailAddress'];
$HomeAddress=$_POST['requiredHomeAddress'];
$SecurityClearance=$_POST['requiredSecurityClearance'];
$Education=$_POST['requiredEducation'];
$ProfessionalExperience=$_POST['requiredProfessionalExperience'];
$ProfessionalLicenses=$_POST['requiredProfessionalLicenses'];
$ComputerProficiency=$_POST['requiredComputerProficiency'];
$Miscellaneous=$_POST['Miscellaneous'];

$errors = array();

$EmailAddress = trim($EmailAddress);
$_name = "/^[-!#$%&\'*+\\.\/0-9=?A-Z^_`{|}~]+";
$_host = "([-0-9A-Z]+\.)+";
$_tlds = "([0-9A-Z]){2,4}$/i";

if (trim($_POST['requiredFirstName']) == "") {
	$errors[] = "First name is required.";
}
if (trim($_POST['requiredMiddleInitial']) == "") {
	$errors[] = 'You did not fill in your middle initial.';
} 
if (trim($_POST['requiredLastName']) == "") {
	$errors[] = 'You did not fill in your last name.';
} 
if (trim($_POST['requiredTelephoneNumber']) == "") {
	$errors[] = 'You did not fill in your telephone number.';
}
if(preg_match($_name."@".$_host.$_tlds,$email)){
	$errors[] = 'Your email address is not in the correct format.';
}
if (trim($_POST['requiredEmailAddress']) == ""){
	$errors[] = 'You did not fill in your email address.';
} 
if (trim($_POST['requiredHomeAddress']) == "") {
	$errors[] = 'You did not fill in your home address.';
} 
if (trim($_POST['requiredEducation']) == "") {
	$errors[] = 'You did not fill in the education field.';
} 
if (trim($_POST['requiredProfessionalExperience']) == "") {
	$errors[] = 'You did not list your professional experience.';
} 
if (trim($_POST['requiredProfessionalLicenses']) == "") {
	$errors[] = 'You did not list your professional licenses and certifications.';
} 
if (trim($_POST['requiredComputerProficiency']) == "") {
	$errors[] = 'You did not state your computer proficiency.';
} 

if (count($errors) == 0) { 
	// no errors, send emails
	//verify EmailAddress is actually valid
	$to = "no1@sumplace.com";
	$subject = "Online Resume Submittion";
	$EmailAddress=$_POST['EmailAddress'];//reset EmailAddress
	$from = "From: ".$EmailAddress;

	$message = "First Name: \n".$FirstName." ";
	$message .= "\n\n\nMiddle Initial: \n".$MiddleInitial." ";
	$message .= "\n\n\nLast Name: \n".$LastName." ";
	$message .= "\n\n\nTelephone Number: \n".$TelephoneNumber." ";
	$message .= "\n\n\nEmail Address: \n".$EmailAddress." ";
	$message .= "\n\n\nHome Address: \n".$HomeAddress." ";
	$message .= "\n\n\nSecurity Clearance: \n".$SecurityClearance." ";
	$message .= "\n\n\nEducation: \n".$Education." ";
	$message .= "\n\n\nProfessional Experience: \n".$ProfessionalExperience." ";
	$message .= "\n\n\nProfessional Licenses: \n".$ProfessionalLicenses." ";
	$message .= "\n\n\nComputer Proficiency: \n".$ComputerProficiency." ";
	$message .= "\n\n\nMiscellaneous: \n".$Miscellaneous." ";

	mail($to, $subject, $message, $from); //Send Email 
	echo "Thank you for your application, we will be in contact with you shortly if you meet the job description requirements.";
	echo '<meta content="4; URL=index.htm" http-equiv="Refresh" />'; //go back to homepage after they read the thank you message
}
 else {
	// there are errors. display them.
	echo "Please correct the following errors:<BR>";
	echo implode('<BR>',$errors);
}
}
?>

and here is a sample from the form

<textarea name="requiredEducation" id="requiredEducation" value="value="<?php echo isset($_POST['requiredEducation']) ? $_POST['requiredEducation'] : '';?>"" rows="4" cols="85"></textarea>

add this to your script (above where you call the alert() functions):

function alert($msg){

$msg = htmlentities($msg, ENT_QUOTES);

if (!empty($msg)){

echo '<script type="text/javascript">
alert("Error: ' . $msg . '")
</script>';

}}

EDIT: NVM that was for your original script lol

thesaleboat · August 27, 2008

i took out the javascript, but you think i could do this instead of having it echo? because the echo never happens and it just redirects to index.htm

HEY! Thanks man... I can finally go home now , is there any way to have the page scroll back to the bottom if there is an error? so that the user can see the problem?

thesaleboat · August 27, 2008

Thanks again Andy-H, im gonna head home now but ill check back tommorrow.

Andy-H · August 27, 2008

You can redirect it to page.php#errors and add

else {

echo '<div align="center" name="errors">The following errors have occurred:<br /><br />';

for ($i=0; $i < count($errors); $i++){

echo '<font color="red">' . $errors[$i] . '</font><br />';

}

echo '</div>';

}

?>

Andy-H · August 27, 2008

else {

echo '<div align="center" name="errors">The following errors have occurred:<br /><br />';

for ($i=0; $i < count($errors); $i++){

	echo '<font color="red">' . $errors[$i] . '</font><br />';

}

echo '</div>';

}
}
?>
