help with $_POST[' ']

seddon

Im very new to php, but im tring to get a simple form to work with the below code. I know registered_globals is turned off so looking at other posts i saw one about using $_POST array. instead of just using the variable.

I get the following error message:

Parse error: parse error, expecting T_STRING' orT_VARIABLE' or `T_NUM_STRING' in /homedir/holly-s31/lgseddon/public_html/forms/form2.php on line 7

form.php

form2.php

<html>
<head>
<title>reading from form.php</title>
</head>
<body>
<?php
print "welcome : <b>$POST['name']</b><p>\n\n";
print "Your address is:<P>\n\n<b>$POST['address']</b>";
?>
</body>
</html>

Another way I read about was using $http_POST_VARS, if i use the below code it does print out the text I enter in my forms but i dont know how to access each element individualy.

<?php
foreach ( $HTTP_POST_VARS as $key=>$value ) {
print "$key : $value<BR>\n";
}
?>

can somebody help please?

thanks

simply change the names of your inputs from $_POST['name'] to just name and then do the same to address.

What you are doing here is telling PHP how to refer to them not actually calling data.

seddon

if i change the from $_POST['name'] to just name it doesn't display anything.

any other ideas?

mystrymaster

on the form

also try

because you might be getting a conflict with name being a reserved word or something

Leave the $_POST['name'] in the echo the same

Should work (you don't need <?php btw, only <? which is better because it makes your script slightly smaller 😛)...

<html> 
<head> 
<title>test form</title> 
</head> 
<body> 
<form action="form2.php"> 
<input type="text" name="name"> 
<br> 
<textarea name="address" rows="5" cols="40"> 
</textarea> 
<br> 
<input type="submit" value="Enter"> 
</form> 
</body> 
</html>

<html> 
<head> 
<title>reading from form.php</title> 
</head> 
<body> 
<? 
print "welcome : <b>$name]</b><p>\n\n"; 
print "Your address is:<P>\n\n<b>$address</b>"; 
?> 
</body> 
</html>

Or if you want them both in the same script... 🙂

<html> 
<head>
<?
if ($submit) {
?><title>reading from form.php</title> 
</head> 
<body> 
<? 
print "welcome : <b>$name]</b><p>\n\n"; 
print "Your address is:<P>\n\n<b>$address</b>";
} else {
?><title>test form</title> 
</head> 
<body> 
<form action="form.php"> 
<input type="text" name="name"> 
<br> 
<textarea name="address" rows="5" cols="40"> 
</textarea> 
<br> 
<input type="submit" value="Enter"> 
</form><?
}
?></body> 
</html>

Good luck! 🙂

Sorry, still having problems the latest code ive tried is below, if i use just $variable, i get nothing in the output and if I use $_POST['ename'] i get a parse error.

I did notice when I used blob's code that it put the info id entered in the address bar, but still not on the page. i thought it went in the address bar if you used method=get.

I just cant seem to get the variables to pass back to the next form.

<html>
<head>
<title>Form</title>
</head>
<body>
<form action="links2.php" method="POST">
Enter name: <br><input type="text" name="ename" size=50>

<br><br>
Enter email: <br><input type="text" name="email" size=50>
<br><br><br>
<input type="submit" value="Continue">
<input type="reset" value="Clear Form">
</form>
</body>
</html>

<html>
<head>
<title>Input from linksform.php</title>
</head
<body>
<?
print "Link One: <b>$_POST['ename']<p>;
print "Link Two: <b>$email";
?>
</body>
</html>

actually <?php ?> is much better because it can't be confused with other scripting languages... <?php ?> is standard

at the top of the page you are submitting to

try this:

<pre>
<?php
   print_r($_POST);
?>
</pre>

it will show you what you actually have in your posted fields... which might be helpful

ednark

print "Link One: <b>$_POST['ename']<p>;

it looks like you forgot an ending "

print "Link One: <b>$_POST['ename']<p>";

seddon

thanks for the help ive got it working now, i changed it from 'ename' to just ename

print "Name: $POST[ename]";
not
print "Name: $POST['ename']";

you can also wrap complex variables in {} within a string, this will work with objects.

" this is a string with the value {$_POST['some_var']} "
" this is a string with the value {$obj->some_var} "

this has might make for easier reading .. and will allow you to use class functions from withing the string
