PHP Four - Working with HTML Forms
July 08, 2012 07:53PM
I found an error in php4p7.html - 7. Checking if the Submit button was clicked.

The name of the submit button is wrong.

The line in red: if (isset($_POST['Submit'])) {
should be: if (isset($_POST['Submit1'])) {

Hi Sandra, is your browser reading the script and not your server?, if so, don't click on the file to open it, launch your server firstly, then call
the html file eg. localhost/order.html (wherever the html doc is located) or click here to your launch your server>> http://localhost/order.html,
fill in your order form then try it

Hi Sandra

I tried your script and it gave me the same error, I changed the method to "post" and it worked fine. In the process script you're telling php your Variable is $_POST['quantity'] and $_POST['item'], but you haven't told your form to Post the info. See below. Hope this helps. 

Language: PHP
<html>
<head>
<title></title>
</head>
<body>
<h4>Art supply order form</h4>
<form action = "process.php" method ="post">
Item : <select name = "item">
<option>Brushes</option>
<option>Paint</option>
<option>Erasers</option>
</select>
Quantity: <input name ="quantity" type ="text" />
<input type="submit"/>
</form>
</body>
</html>

I would like to know if the following:

VALUE="<?PHP print $username; ?>"

shouldn't have been written like this?

VALUE="<?php print ($username); ?>"

I couldn't really see what it does. Nothing is returned when you click the button.

Is there an easier way to check the 5 usernames? 

Language: PHP
<html>
<head>
<title>A BASIC HTML FORM</title>
 
<?php
if (isset($_POST[';Submit1';])) {
$username=$_POST[';username';];
 
if ($username=="fox") {
print ("Welcome back, friend!");
}
else if($username=="wolf") {
print ("Welcome back, friend!");
}
else if($username=="jackal") {
print ("Welcome back, friend!");
}
else if($username=="hound") {
print ("Welcome back, friend!");
}
else if($username=="dog") {
print ("Welcome back, friend!");
}
else {
print ("You';re not a member of this site");
}
}
?>
 
</head>
<body>
 
<FORM NAME="form1" METHOD="POST" ACTION="formexercise2.php">
 
<INPUT TYPE="TEXT" Name="username" VALUE="username">
 
<INPUT TYPE="Submit" Name="Submit1" VALUE="Login">
 
</FORM>
 
 
 
</body>
</html>

Have completed this section too, was having problems with getting the isset function right for a GET method, but after checking the syntax correctly, I now fully comprehend it. I think the POST method despite being secure is the best to use for submitting data.

To help with error checking it is sometimes a good idea to use $_GET until you find the error, because then you can see if the variables collected by a form, for example, is being passed correctly, and what it is passed as 

Language: PHP
//URL looks like this on receiving page
file.php?init=TM&sname=vdMerwe &email=here@there.com&hits=95

It is easy to see the values are being correctly captured in the form and passed, and also how you need to capture it. 

Language: PHP
$initials=$_GET[';init';]; //After error checking, change the form to post and this to $initials=$_POST[';init';];
$surname=$_GET[';sname';]'; //After error checking, change the form to post and this to $surname=$_POST[';sname';]
//etc.

print can use brackets, your choice. IF nothing is returned it is not because of this.

PHP Four completed finally, really struggled here - I tried different ways of setting up a form for the 5 usernames, including conditional logic and switch statements. On to chapter 5.
