[SOLVED] How are these data types returned?

[clanstyles]

How is an html event like this returned?

 

  <select name="rank" size="6" id="rank" multiple="1">

  <?php

  $result = mysql_query("SELECT * FROM `ranks`") or die(mysql_error());

  while($res = mysql_fetch_array($result))

  {

  if($res['rank'] != "Guest" || $res['rank'] != "Administrator")

  echo "<option value=\"0\">".$res['rank']."</option>";

  }

  ?>

  </select>

 

If i select one and do a print out $_post['rank']; its always blank.

 

Whats up ? How do these types of things work?

[per1os]

$_POST should be capitol and the value is what would be printed out. It should print "0" ...really no matter what as long as they aren't a guest or an admin.

Well I added echo "hi"; it doesn't work eathier.... if(isset($_POST['Submit'])) isan't wokring..

[Yesideez]

You mean how do drop-down selection boxes work?

 

First you define a list of options:

<option value="X" selected="selected">Y</option>

X would be a value unique to that option which is used to identify it.

Y is the text that the user would see in the list

The selected="selected" is only used once and tells the browser which one to display as default. This can be omitted and if it is, it'll use the very first as the default option.

 

You can have as many of those options as you want.

 

Once you've got the list made you need to surround them with some more HTML to activate them:

<select name="N">O</select>

N is th name which you use to identfy with $_POST or $_GET

O is the list of options you just built above

 

Hope that explains it well enough.

Is display_Errors set to on via www.php.net/ini_set  and error_reporting(E_ALL)  It sounds like you have an error in your code.

 

Try doing a

 

print_r($_POST);  at the top.

[Carterhost]

while($res = mysql_fetch_array($result))
 {
    if($res['rank'] != "Guest" || $res['rank'] != "Administrator")
       echo "<option value='"$res['rank']"'.>".$res['rank']."</option>";
 }

 

That will populate your $_POST['rank'] with the rank, as long as it's not Guest or Administrator.

[Yesideez]

The case of "N" must be the same in both SELECT and $_POST/$_GET. If you use name="cats" and have $_POST['Cats'] then they won't be the same.

[Yesideez]

1. In your FORM declaration are you using method="get" or method="post"?

2. What did you call your SUBMIT button and what have you called it in your $_POST/$_GET?

K heres what I hav enow, btw post.

 

if(isset($_POST['Submit']))
{
echo sizeof($_POST['deleterank']);
}
?>
<form id="delrank" name="delrank" method="post" action="?page=accountarea&place=adminarea&action=delranks" enctype="multipart/form-data">
  Rank Name(s):
  <label>
  <select name="deleterank" size="6" id="deleterank" multiple="0">
  <?php
  $result = mysql_query("SELECT * FROM `ranks`") or die(mysql_error());
  while($res = mysql_fetch_array($result))
  {
  	if($res['rank'] != "Guest" && $res['rank'] != "Administrator")
  		echo "<option value=\"".$res['id']."\" id=\"rank\">".$res['rank']."</option>";
  }
  ?>
  </select>
  </label>
  <p>
    <label>
    <input type="submit" name="Submit" id="Submit" value="Submit" />
    </label>
  </p>
</form>

 

Now, I need to get lets say I click 3 at once. How do I get ALL three? It isan't puting them, into an array it just selects one. of the 2 i click or something like that.

[Yesideez]

btw, if you right-click your browser and select "View source" you can see the HTML that your script has made and see what values the options have been given.

[per1os]

This may be causing the problems

 

enctype="multipart/form-data">

 

Unsure but try removing that and see if you still have a problem (do a print_r or a vardump on the $_POST)

[clanstyles]

Removing the encrypt tag didn't work and also the print_r / var_dump only returns the one value. If you chose more than one it just returns hte last one.\

 

And yeah they show right. On click it is supposed to grab the ID so i can do for($i=0;$i<sizeof($array);$i++)

{

mysql_query("DELETE FROM `ranks` WHERE `id`=$array[$i]");

}

[Yesideez]

Can you show the HTML the script makes? Need to make sure you're actually getting values put in the options. If you're not it explains why you're not getting anything back.

Change this line and try again:

<select name="deleterank[]" size="6" id="deleterank" multiple="multiple">

 

EDIT:: btw, I made two changes.
