[SOLVED] POST & GET help

jamesxg1 · February 4, 2009

hiya,

i have a php script called profile.php basically when your viewing a users profile it will look like this profile.php?username=PERSONS USERNAME but what i need to do is post the username that is at the end of the url what ever it may be and display it on another page in a text box how do i do this ?

aebstract · February 4, 2009

$_GET['username'];

or you can set it as a variable.

$username = $_GET['username'];

jamesxg1 · February 4, 2009

$_GET['username'];

or you can set it as a variable.

$username = $_GET['username'];

Iv tryed it doesnt work ,

all i need it to do is post what ever is at the end of the url eg. profile.php?username=JAMES

so it will post JAMES

to what ever page i use the GET on and then i can display it in a text box

Any ideas ?

aebstract · February 4, 2009

$_GET['variable'] is the way to do this.. if it won't work then you have something set wrong on your server, I'm not too sure on what you have to do to set it up but I'm sure someone will post it.

gevans · February 4, 2009

can you show some code?

Maq · February 4, 2009

Page with the link:

$username = "james";
?>

profile.php:

$username = $_GET['username'];
?>

jamesxg1 · February 4, 2009

Ok heres the code

Profile.php

<?php session_start(); 

require("../db/db.php"); //include database file
require("../db/config.php"); //include configuration file
require("../db/util.php");
require("../db/settings.php");

isloggedin();
accessneeded("C");

?>
<?php
$username = $_POST['username'];
?>
<?php
$id = mysql_real_escape_string($_GET['id']);
$username = mysql_real_escape_string($_GET['username']);
$sql = "SELECT * FROM `users` WHERE `id`='$id' OR `username`='$username' LIMIT 1";
$query = mysql_query($sql);
if(mysql_num_rows($query) > 0){

//display content
while ($row = mysql_fetch_assoc($query)) {
$id = $row['id'];
$photo = $row['photo'];
$gender = $row['gender'];
$email = $row['email'];
$firstn = $row['firstname'];
$lastn = $row['lastname'];
$dobd = $row['dobDay'];
$dobm = $row['dobMonth'];
$doby = $row['dobYear'];
$username = $row['username'];
$music = $row['music'];
$movies = $row ['movies'];
$scaredof = $row['scaredof'];
$field1 = $row['field1'];
$field2 = $row['field2'];
$field3 = $row['field3'];
$field4 = $row['field4'];
$field5 = $row['field5'];
$fieldb1 = $row['fieldb1'];
$fieldb2 = $row['fieldb2'];
$tagline = $row['tagline'];

}

Where is the link on Profile.php that sends the user to Compose.php?

Maq · February 4, 2009

I'm confused, you want the current username in the text box or you want it hidden with the value of $user?

In compose.php:

[code]

You need to give it the correct value which I'm almost positive is $user or you could give it the username from SESSION

Change it to:

In profile.php you need to use the POST method not the get method...

$username = mysql_real_escape_string($_POST['username']);

Where is the link on Profile.php that sends the user to Compose.php?

I guess he wanted a text field but I have no clue...

Ok basically this is what i mean

in profile.php when someone is viewing a profile the profile username is made into a varible

so what i need to do is post that varible to compose.php eg.

Profile.php

<?php

$usernamepost = $_POST['$username'];

?>

Then on my Compose.php it will look like this

<?php

$usernamepost = $_GET['$username'];

?>

And then i can do this

If you get what i mean lol ?

Where is the link on Profile.php that sends the user to Compose.php?

I guess he wanted a text field but I have no clue...

Yea, I'm a bit lost as well!

Yes, but where on profile.php is the link to compose.php?

Yes, but where on profile.php is the link to compose.php?

Im not using a link i am using a ajax popup box and its basically like a IFrame that will show the compose.php in it, and what i will do is in compose.php where it says mysql_query blah blah blah instead of it saying (reciever) Values ($reciever) i will put $username so it will input the username of the person's profile they was viewing

So is the user clicking a link from somewhere (not mentioned) to get to compose.php? Then you want to store the username in a hidden field in compose.php and pass it to profile.php?

So your steps should look like this:

Profile.php

$usernamepost = $_POST['usernamepost'];
?>

Then on my Compose.php it will look like this

$usernamepost = $_GET['$username'];
?>

And then i can do this

PS - Never use short tags, always use <?php.

didnt work ,

i have found a easyer way around this

this is the link on profile.php

<a href="../messages/compose.php" class="lbOn">Send Message</a>

if i change the link to this

<a href="../messages/compose.php?username=$username" class="lbOn">Send Message</a>

how would i make it so that in the compose.php it will get the $username part from that ?

$user = $_GET['username'];
