accessing variables after i "Submit" the form

levans

How can i get the variable $name after i press the submit button. The first echo of $name gives me the value, the second doesnt

$name = $_GET['name'];//get this var from the url this page

//this prints fine, it prints whatever user is logged in..
echo( "Here are your contacts user: $name" );

$db = mysql_connect("localhost", "root");
mysql_select_db("contacts");

if($_POST['Submit'] == 'Add Contact')
{
//this has no value?????? help..
echo($name);
}

//my form is down here somewhere...

<form method="post" action="add.php">
...blah blah blah, the action is the same page so it goes from add.php to add.php

nemonoman

show us the html for your submit button...something like <input type=submit ...etc.

levans

<input type="text" name="fname_form">First Name
<input type="text" name="lname_form">Last Name
<input type="text" name="phone_form">Phone Number <input type="text" name="email_form">

</form>

if($_POST['Submit'] == 'Add Contact')
{
//this has no value?????? help..
echo($_POST['name']);
}

I tried that, it doesnt echo anything??🙁

levans

would i have to feed the $name value into the URL???

have you tried lowercase 'post' in place of 'POST'?

levans

just tried..

echo($_post['name']);

doesn't work, tried some different variants of it too..

😕 😕 😕

nemonoman

add this code to add.php and show us the output, please?

print_r($POST);
print_r($REQUEST);

Array ( [fname_form] => bill [lname_form] => gates [phone_form] => 506-455-4555 [email_form] => bill@microsoft.com [address_form] => 5 microsoft way [Submit] => Add Contact ) Array ( [fname_form] => bill [lname_form] => gates [phone_form] => 506-455-4555 [email_form] => bill@microsoft.com [address_form] => 5 microsoft way [Submit] => Add Contact )

levans

and my complete code for add.php is:

<p>Enter in the correct information to add a new contact to your list..</p>

<form method="post" action="add.php">
<input type="text" name="fname_form">First Name
<input type="text" name="lname_form">Last Name<
<input type="text" name="phone_form">Phone Number
<input type="text" name="email_form">Email Address
<input type="text" name="address_form">Address

</form>

<?php
$name = $_GET['name'];

echo( "Here are your contacts user: $name" );

$db = mysql_connect("localhost", "root");
mysql_select_db("contacts");

if($POST['Submit'] == 'Add Contact')
{
//echo("should be here!");
//echo($post['name']);

print_r($_POST); 
print_r($_REQUEST);

}
?>

nemonoman

based on the variables:

if($_POST['Submit'] == 'Add Contact') {

will test true, and it will run.

But here's what runs:

echo($name);

$name at this point is not defined.

What you want to do is add a line of PHP code to your form generation code:

<? echo "<input type=hidden name=name value=$name>" ?>

Then when a user clicks the submit button, you can

echo $_POST['name'];

<?php
$name = $_GET['name'];
?>

<p>Enter in the correct information to add a new contact to your list..</p>

</form>

<?php
echo( "Here are your contacts user: $name" );

$db = mysql_connect("localhost", "root");
mysql_select_db("contacts");

if($POST['Submit'] == 'Add Contact')
{
//echo("should be here!");
//echo($post['name']);

print_r($POST);
print_r($REQUEST);
}
?>

BUMP...sorry i had to work crazy hours all week, this last suggestion didn't work either. No errors, just didn't give the variable a value...

Im posting my whole source file here...add.php

<body>

<p>Enter in the correct information to add a new contact to your list..</p>

<input type="text" name="fname_form">
First Name<br /><input type="text" name="lname_form">
Last Name<br /><input type="text" name="phone_form">
Phone Number<br /><input type="text" name="email_form">
Email Address<br /><input type="text" name="address_form">
Address<br />

<? echo "<input type=hidden name=thename value=$name>" ?>

</form>

<?php

$name = $_GET['name'];//i get this from the last file in the URL

//$name2 = $name;

echo( "Here are your contacts user: $name" );

$db = mysql_connect("localhost", "root");

mysql_select_db("contacts");

if($_POST['Submit'] == 'Add Contact')
{
echo("should be here!");

$somevar =  $_POST['thename']; 
echo("The var is $somevar");//this prints nothing??

}

mysql_close();
?>

</body>
</html>

nemonoman

your code says:

$somevar = $_POST['thename'];

What do you expect $somevar to be?
'thename' doesn't appear anywhere in your form.

if you said:
$somevar = $_POST['lname_form'];

$somevar = $_POST['fname_form'];

Maybe $somevar would have a value.

But since you don't have anything that says

What do you expect $_POST['thename'] to contain?

You might as well say

$somevar = $_POST['I_am_complete_and_total_idiot'];

You're looking for the values of variables you never $_POSTed.

levans

you told me to put this line in...

<? echo "<input type=hidden name=thename value=$name>" ?>

i thought if I put that line in the <form> then it would post these values...guess not

im sorry im not a php master like you, im just taking my first web programming course and I thought this site would be helpful...

nemonoman

OK...sorry, so you have. I missed that, sorry. But look:

First you put in:

<? echo "<input type=hidden name=thename value=$name>" ?>

BUT at this point $name has no value!!

ONLY a FEW LINES LATER do you get around to giving it a value:

<?php

$name = $_GET['name'];//i get this from the last file in the URL

Look:

$name = $_GET['name'];//
<? echo "<input type=hidden name=thename value=$name>" ?>

That should work.

levans

thx man, worked.
