[Resolved] return the user back to form i

cedtech23

I used the script below to make sure that users have certain fields fill out. I want to return the user back to the form html page if any of the condition listed below are true: with the error messages showing. How can this be done

$errmsg="";
if ($_POST[sender_name]== "") {
$errmsg .= ("Enter your name<BR />");
}

if ($_POST[sender_email]== "") {
$errmsg.= ("Enter your email<BR />");
}

if ($_POST[sender_phone]== "") {
$errmsg.= ("Enter your phone number<BR />");
}

if ($_POST[OS]== "") {
$errmsg.= ("Enter your Operating system<BR />");
}

if ($_POST[message]== "") {
$errmsg.= ("Please, Fill Tell us about your Problem<BR />");
}
if ($errmsg!="") {
echo $errmsg; }

Get the page itself to process the form, e.g. by setting the form action to $_SERVER['PHP_SELF']

are u also performing these checks BEFORE submiting the form ...via javascript. i consider that to be the easier way. but if u still want to do a check at server side too... then the solution given by laserlight sounds easiest. if the page itself is processing the form then u cud use the $_POST values to re-populate the form and make the user enter missing fields.

if you leave Form Action tag blank it will submit the from to itself. when clicking submit , but its better to give it a action.
by defalt it will submit itself to the same page.

The error I am receiving from the browser when I hit sumbit with none of the field fill with info is:

Not Found
The requested URL /$_SERVER['PHP_SELF'] was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I must be using the action="$_SERVER['PHP_SELF']"
wrong or I place the <? ?> in the wrong location. Do you have an idea why I am getting this error?

Listed below is the enter PHP script: I named the file support.php

Okay I took Zapa hint and used the action="support.php. works great but because of the position of my <? ?> statements the first time the user logs on they get:

Enter your name
Enter your email
Enter your phone number
Enter your Operating system
Please, Fill Tell us about your Problem

at the botton of the form. I don't want the users to get these messages the first time they log on to the support.php page I want them to get these messages if they apply after they fill out the for and hit the sumbit button. I tried positioning the php in different locations with no luck. Does someone have a way to resolve this little bug in my script??

Listed below is the PHP script:

<html>
<head>
<title> Support Form</title>

<p><strong>Name:</strong> <input name="sender_name" type="text" size="30">

$errmsg.= ("Enter your phone number<BR />");
}

if ($_POST[OS]== "") {
$errmsg.= ("Enter your Operating system<BR />");
}

if ($_POST[message]== "") {
$errmsg.= ("Please, Fill Tell us about your Problem<BR />");

if ($errmsg!="") {

}

If you wanted to use the $_SERVER['PHP_SELF'] method, your form tag would look like this:

cedtech23

In the end this both these methodes wroked for me

but I am still getting the the form plus this info:

Enter your name
Enter your email
Enter your phone number
Enter your Operating system
Please, Fill Tell us about your Problem

when I first access the form. How come it's not waiting for the user input first?? and how can I correct the problem??

PallaviDalvi

enclosing the IFs in
if (sizeof($_POST)) will solve ur prob.

In the end I used the following:

before the:

this allowed me to enclose all my PHP code in

if ($_POST[check] == "true") {

My PHP code

}

// Thanks for all the input
