I have a [php]$_GET[‘status’][/php] variable and a dropdown list : [php]$_GET[‘amount’][/php].
Every time i click on a link. For example : Spullen Aangeboden .
I have to do this :
[php]if($_GET[‘amount’] != “”)
$amount = “&amount=”.$_GET[‘amount’];
else
$amount = “”;
if($_GET[‘status’] != “”)
$stat = “&status=”.$_GET[‘status’];
else
$stat = “”;[/php]
So for every link I have to reset this. Is there another way to make it stay the last set value ?
You can do it with the $_POST of your select boxes name and just set the value to what was selected previously…
But their’s really no automatic way of doing it in php that I’m aware of. If you were using Microsoft .NET you just turn on viewstate and it will retain it for you automatically.
I’m not entirely sure what the problem is, but perhaps you can look into these options
Using $_REQUEST instead of $_GET
Using http_build_query()
Using $_SERVER[‘QUERY_STRING’]
What I mean is this: When I have a dropdown list with the name ‘amount’ with a standard value of ‘24’ and I change the value to 12. Then the value should stay 12 if I click on a link : a href="indexbody.php. But when I click on this link the value of the dropdown list is reset back to 24. So for every link I click, I have to do this :
[php]if($_GET[‘amount’] != “”)
$amount = “&amount=”.$_GET[‘amount’];
else
$amount = “”;
[/php]
a href=“indexbody.php?$amount”
Do you understand me ?
You want this:
[php]
<?php if (isset($_GET['amount'])){ echo "{$_GET['amount']} "; } ?> var1 var2 [/php]Another way of doing it.
[php]<?php echo (isset($_GET['amount'])) ? '' . '$' . number_format($_GET['amount'], 2) . '' : NULL; ?>[/php]
I have this right now :
[php]function setNumberPerPage($id) {
$options = array(
6 => 6,
12 => 12,
18 => 18,
24 => 24,
30 => 30
);
if($_GET['service'] != "Info" && $_GET['service'] != "Bericht") {
echo"<form name = 'form' action = 'indexbody.php' method = 'GET'>
<label for = 'amount' id = 'label'>Aantal: </label>
<select id='$id' name='amount' onchange='setAmount(this)'>";
foreach($options as $key => $value) {
$selected = $_GET['amount'] == $key ? 'selected' : '';
if($key == 24 && !$_GET['amount'])
$selected = 'selected';
echo"<option value = '".$key."' ".$selected.">".$value."</option>";
}
echo"</select></form>";
}
}[/php]
[code][/code]
What should I change to make it work ?
amount is the name of the dropdown list, not mydropdown !
Sorry dude but your solution doesn’t work ! My code, you see above, works. The only problem is, when I have a link : indexbody.php?service=test1&amount=12. Amount is the name of the dropdown list with a standard value of 24! And if I have another link : indexbody.php?service=test2 witch doesn’t set amount. If I click on the second link, the dropdown list is reset back to 24.
So for every link i have to reset the URL parameter amount : indexbody.php?service=test2&amount=12. Isn’t there a way it automatically stays 12 ?
Thank you !
Post the entire code you are using.
This is my indexbody.php !

Kevin ?
Your code is not working because you are not using brackets with your if/else statements so you have multiple encapsed whitespace errors. You need to either use brackets or enclose the variables that need it in brackets.
The brackets have nothing to do with it.
The brackets and lack thereof has everything to do with it.
Show me this code working without adding additional brackets anywhere. Not going to happen.
