need help with serialize() again

[gdfhghjdfghgfhf]

here's what i'm trying to do

 

i have a field in my database (options in table quebec_calendarcustomfield) used in vbulletin for calendar custom fields. I want to allow a group of users to add and delete fields...

 

So now i'm trying to make a page where my users are able to delete a field.

 

All fields are serialized and stored in quebec_calendarcustomfield WHERE calendarcustomfieldid = '1'

 

so i tryed to unserialize it, do a str_replace to delete the field i want, and serialize it back....

 

but i'm stuck at serializing back, i can't find out how to serialize the whole array

 

include("db.php");
$query = "SELECT options FROM quebec_calendarcustomfield WHERE calendarcustomfieldid = '1'";
$res = mysql_query($query) or die(mysql_error());  
while($row = mysql_fetch_array($res)) { 
$a = $row["options"];

$unseri = unserialize($a);

foreach($unseri as $value)
{
$hmm = str_replace("$legroupe", "", "$value");
   echo $hmm;
} 

echo "<br><br>";
$uhh = serialize($value);
echo $uhh;

$cc = mysql_real_escape_string($uhh);
$zxc = "UPDATE quebec_calendarcustomfield SET options = '$uhh' WHERE calendarcustomfieldid = '1'";
$res = mysql_query($zxc) or die(mysql_error());  
}

 

$legroupe is a defined $_GET value and it contains the line i want to delete

 

$a = $row["options"];  is the serialized array of ALL the fields, including the one i want to delete

help plz?

[uniflare]

you could use unset();

 

$unseri = unserialize($a);
print_r($unseri); echo("<br />");

unset($unseri[$legroupe]);
print_r($unseri); echo("<br />");

$uhh = serialize($unseri);
print_r($uhh);

 

hope this helps,

hmmm it doesnt work for me, the thing to delete ($legroupe) is still here

 

what is unset? it does the same thing i was doing with str_replace?

 

btw, $legroupe is not serialized, but $a (row["options"]) is

give us the output source, what do $a look like? echo it out for us

[gdfhghjdfghgfhf]

serialized version of $a:

a:7:{i:1;s:18:"111111111111111111";i:2;s:18:"222222222222222222";i:3;s:13:"3333333333333";i:4;s:13:"4444444444444";i:5;s:14:"55555555555555";i:6;s:12:"666666666666";i:7;s:12:"777777777777";}

oh ok try this:

 

$unseri = array_flip(unserialize($a));
unset($unseri[$legroupe]);
$unseri = array_flip($unseri);

$uhh = serialize($unseri);
