Preventing blank form results

JCS1988 · September 12, 2007

Hello, I am fairly new to PHP and only know a bit. I was able to come up with a form that users can fill out for a design request for a clients web site. The form is handled by another processor page and the information is then sent to the e-mail address for the company, right now It's sent to my e-mail for testing purposes. The form works great when they enter the information and submit, but if a users happens to visit the processer page it sends the form out blank. I understand that it couldn't post any data from the previous page because it was never given any information, but how can I make it so that the processor page only sends out the email when there is actual information to send. I know there is a way to do all the processing within one page but I am not sure how. If someone could please help me out, and maybe modify the scripts I have attached that would be awesome! Thanks in advance!

I have this code inside the header:

		 <!-- validate -->
	<SCRIPT type=text/javascript>
	<!--
		function validateField(fieldId, fieldBoxId, fieldType, required)
		{
			fieldBox = document.getElementById(fieldBoxId);
			fieldObj = document.getElementById(fieldId);

			if(fieldType == 'text'  ||  fieldType == 'textarea'  ||  fieldType == 'password'  ||  fieldType == 'file'  ||  fieldType == 'phone'  || fieldType == 'website')
			{	
				if(required == 1 && fieldObj.value == '')
				{
					fieldObj.setAttribute("class","mainFormError");
					fieldObj.setAttribute("className","mainFormError");
					fieldObj.focus();
					return false;					
				}

			}


			else if(fieldType == 'menu'  || fieldType == 'country'  || fieldType == 'state')
			{	
				if(required == 1 && fieldObj.selectedIndex == 0)
				{				
					fieldObj.setAttribute("class","mainFormError");
					fieldObj.setAttribute("className","mainFormError");
					fieldObj.focus();
					return false;					
				}

			}


			else if(fieldType == 'email')
			{	
				if((required == 1 && fieldObj.value=='')  ||  (fieldObj.value!=''  && !validate_email(fieldObj.value)))
				{				
					fieldObj.setAttribute("class","mainFormError");
					fieldObj.setAttribute("className","mainFormError");
					fieldObj.focus();
					return false;					
				}

			}



		}

		function validate_email(emailStr)
		{		
			apos=emailStr.indexOf("@");
			dotpos=emailStr.lastIndexOf(".");

			if (apos<1||dotpos-apos<2) 
			{
				return false;
			}
			else
			{
				return true;
			}
		}


		function validateDate(fieldId, fieldBoxId, fieldType, required,  minDateStr, maxDateStr)
		{
			retValue = true;

			fieldBox = document.getElementById(fieldBoxId);
			fieldObj = document.getElementById(fieldId);	
			dateStr = fieldObj.value;


			if(required == 0  && dateStr == '')
			{
				return true;
			}


			if(dateStr.charAt(2) != '/'  || dateStr.charAt(5) != '/' || dateStr.length != 10)
			{
				retValue = false;
			}	

			else	// format's okay; check max, min
			{
				currDays = parseInt(dateStr.substr(0,2),10) + parseInt(dateStr.substr(3,2),10)*30  + parseInt(dateStr.substr(6,4),10)*365;
				//alert(currDays);

				if(maxDateStr != '')
				{
					maxDays = parseInt(maxDateStr.substr(0,2),10) + parseInt(maxDateStr.substr(3,2),10)*30  + parseInt(maxDateStr.substr(6,4),10)*365;
					//alert(maxDays);
					if(currDays > maxDays)
						retValue = false;
				}

				if(minDateStr != '')
				{
					minDays = parseInt(minDateStr.substr(0,2),10) + parseInt(minDateStr.substr(3,2),10)*30  + parseInt(minDateStr.substr(6,4),10)*365;
					//alert(minDays);
					if(currDays < minDays)
						retValue = false;
				}
			}

			if(retValue == false)
			{
				fieldObj.setAttribute("class","mainFormError");
				fieldObj.setAttribute("className","mainFormError");
				fieldObj.focus();
				return false;
			}
		}
	//-->

	<!-- end validate -->

Add this to your processor page:

if (sizeof($_POST)==0)
{
header("Location:Form.php");
}
else
{
//put the rest of your processor code here
}

This will redirect you to your form if no post was sent to the page, but if a post was sent it will process.

Thank you! for the part "header("Location:Form.php");" should form.php be something else for this site? I dont have any files named form.php, does that matter?

liebs19 · September 12, 2007

Yeah, change form.php to the location of the file you want to redirect to. It can be anywhere on you site like /forms/input/forminput.php if that is where your file is.

Thanks, works great now.
