There are a few BASIC errors in your script and some questions that I have:

 

1) Never start PHP with "" always use "<?php".

2) Where is your form declared?  You need something like this if you want to submit the form to itself.

</pre>
<form method="POST" action="<?php%20echo%20%24_SERVER%5B'PHP_SELF'%5D;%20?>"><

3) Show us all the code.

4) So basically you want to generate check boxes via a DB, submit it and remember what was checked after submission?

its a big page i cannot show the all the code , form is a big form too so decleration is at the top of the page, dont ruin my topic if you dont know the answer please you said something none of them are usefull for me

First off Maq was just trying to help you without even seeing much of your code. he is trying to show you the proper methods of php. Basically what I see is wrong is that you did not declare $checked. You need to add this:

 

$checked = "";

 

above this:

 

echo "<input type=checkbox $checked name=is[]  value=$r[id] >$r[isadi]<br>";   

 

and change this:

 

echo "<input type=checkbox $checked name=is[]  value=$r[id] >$r[isadi]<br>"; 

 

to this:

 

echo "<input type=checkbox checked=$checked name=is[]  value=$r[id] >$r[isadi]<br>"; 

 

That way it is defined either way.

[dtdetu]

thank you but now it shows every one of them as checked

[Maq]

dont ruin my topic if you dont know the answer please you said something none of them are usefull for me

 

It may not be useful to you, but it's useful to me.  I don't know how your script works, you're the one who's too inept to write a basic PHP script.  So don't worry about me, "ruining" your topic, because I don't like helping ignorant people that are asking for help.

 

Think about how vague your question is

 

but it didnt work can anyone help please

 

You need to learn how to ask a question correctly or no one will be able to help

 

What the hell is "kodu" anyway?!

[ngreenwood6]

did you try this?

 

and change this:

 

Code: [select]echo "<input type=checkbox $checked name=is[]  value=$r[id] >$r[isadi]<br>";

 

to this:

 

Code: [select]echo "<input type=checkbox checked=$checked name=is[]  value=$r[id] >$r[isadi]<br>";

 

if so are you getting any errors or what is happening?

Funny how you can't even figure out the solution to a basic PHP technique that I have sitting right in front of me all because you're an ignorant ass.

 

P.S. - Your code is out of date and probably has many security holes and exploits, have fun with that one jerkoff.

[Maq]

hey idiot Maq its non of your business

 

None of my business?  If it's such a secret why are you posting on a public forum...?  I think you're the idiot.  Besides you're the one in search of answers, I already have them.

You really should stop hating on Maq because he is right about alot of things that he has told you and was just trying to be helpful. He is a positive influence on this community I must say myself. If you are going to be a part of this community you must be open to constructive criticism. Anyways this should help:

 

  <?   
$q=mysql_query("select * from iscesitleri");
echo "    
    
          <table border=0 cellspacing=5 width=80%><tr valign=top><td width=33%>";
$i=1;
while($r=mysql_fetch_array($q))
{
    
?>

<input type="checkbox" <?php if($_POST[is][1] == $r[id]){ echo "checked='$checked'"; } ?> name="is[]"  value="<?php echo $r[id]; ?>" ><?php echo $r[isadi]; ?><br>
       
<?php
    if($i==17) {
        echo   "</td><td width=33%>";
        $i=0;
    }
    $i++;
}
echo "</td></tr></table>";
?>

 

I think that should get it going. Please let me know if it works and if you get an error let me know what it is.

<?php

$query = "select * from iss";
$result = mysql_query($query );

echo "<table border=\"0\" cellspacing=\"5\" width=\"80%\"><tr valign=\"top\">\n";

$records_per_column = ceil(mysql_num_rows($result)/3);
$current_record = 1;

while($record=mysql_fetch_array($result))
{
    if ($current_record==1)
    {
        echo "<td width=33%>\n";
    }

    $checked = (in_array($record['id'], $_POST['is'])) ? ' checked="checked"' : '' ;
    echo "<input type=\"checkbox\" name=\"is[]\"  value=\"{$record['id']}\"$checked />{$record['isadi']}<br>\n";       
    $current_record++;

    if($current_record > $records_per_column)
    {
        echo "</td>\n";
        $current_record = 1;
    }
}

if($current_record != 1)
{
    echo "</td>\n";
}

echo "</tr></table>";
