Hey all,

 

Been a while since ive coded php and am stuck already.

Here is the issue, i have a list being made from the database using id as the identifier. so the link being rendered is client.php?id=1 etc.

 

im trying to use this info to populate the page it directs too using the folowing add on script:

 

<?

$lin = mysqli_connect("*","*","*!","*") or die("Error 1 " . mysqli_error($lin));

 

//consultation:

 

$query = "SELECT * FROM Clients WHERE ID=$id " or die("Error 2 in the consult.." . mysqli_error($lin));

 

//execute the query.

 

$result = mysqli_query($lin, $query);

 

while($row = mysqli_fetch_array($result)) {

$name = $row['1'];

$address = $row['2'];

$city = $row['3'];

$postcode = $row['4'];

$phone = $row['5'];

$email = $row['6'];

 

}

?>

 

Problem is this isnt working and i have no idea why

 

Can anyone help?

Hey Ch0cu3r,

 

thank you for the reply, i updated it to this:

 

$query = "SELECT * FROM Clients WHERE ID=$_GET['id'] " or die("Error 2 in the consult.." . mysqli_error($lin));

 

however now the page no longer loads up?

 

in dreamweaver its telling me i have a syntax error on that line too?

So...the issue is fixed? If so, could you make the thread as solved.

 

For what it's worth, when having a variable like $_GET['id'] work in a double quoted string you can surround the variable with curly brackets:

 

 

<?php
$query = "SELECT * FROM Clients WHERE ID={$_GET['id']} " 
?>

 

Also note that using information from untrusted sources, like the GET variable, without any kind of validations will open your query up for SQL injection attacks. Assuming the ID is a number you could make sure it is with the ctype_digit() function:

There are button under each response to the right. For the response which most closely answers your question, click the one that says "Mark Solved". :)
