Form validation that remembers!

[Anon]

Hello all,

Does anyone know how to validate a form but remember the values that the user entered correctly. I managed to make it validate with this code but the user would have to enter the whole form again. I'd really appreciate an example.

Thanks

Chris

<form action="validform.php4" method="POST">
First name <input type=text name=first_name>
Last name <input type=text name=last_name>

 <input type=submit name=enter value="Submit">
 <input type=reset value="Clear">
 </form>

<?

if($enter) {

if(($first_name&&last_name)=="") {
echo "Please go back and fill in the rest of the form";
exit();
}

}

?>

sure, just do this:

<input type=text name=first_name value="<? echo $first_name ?>">
<input type=text name=last_name value="<? echo $last_name ?>">

Yup.

Just create one form, that has all the error_checking it to start with.

Let the script submit it's information to itself.

At the top of the script you check if this script is called by a submit action or not.
No submit action: print the empty form.
With submit action: print the form with error checking.

your input items would look like this:

echo "<input name=bla value=".$value_from_submit_action.">";
if ($value_from_submit_action!='')
{
echo 'please fill out this value';
};

I understand how to display remembered values for text fields.
How do you display a radio button selection?
Thanks,

<INPUT TYPE="radio" name="radioName" value="true" <? if($radioName=="true") echo "SELECTED" ?>>true
<BR>
<INPUT TYPE="radio" name="radioName" value="false" <? if($radioname=="false") echo "SELECTED" ?>>false

hmm, my bad, I think that's CHECKED, not SELECTED.

Hi folks !
I could not understand this how to remember the values. I am using some java script but it sucks on Netscape so i wanna use some php now.
I am using the same form either wants to add some data into database or update the data then I call another file when user submits the data. what i m doing right now, if some data is missing , i call the same form function with the current values as parameters but this is complex thing as i will have to write a lotta code ..can u please explain a bit for me. I am stuck with js stuff my code looks like this :

function GenerateHTMLForm($reofferType,$formValues,$reqstudy_field,$actionScript, $submitLabel)
{
printf("<FORM onSubmit=\"return checkrequired(this)\" METHOD=post NAME = form1 ACTION=\"%s\"><PRE>\n", $actionScript);
printf("E-mail <INPUT TYPE=text SIZE=40 NAME=reqemail VALUE=\"%s\">
\n", ($formValues) ? $formValues["email"] : "");
printf("<INPUT TYPE=submit VALUE=\"%s\">", $submitLabel );
if ($submitLabel != "MODIFY")
printf("<INPUT TYPE=reset VALUE=\"Cancel\">");
printf("</PRE></FORM>" );
}
