Hello,

i have a page where it shows the current records which status is active usually there are like 30 records active, every records has a check box so you can select it i have made a button so you can print the selected records the user can only select a max of 4 records and the code works fine but if they select less than 4 records the code wont work heres the code.

PHP Code:

foreach($keys as $idx=>$val)
{
    $id1 = $keys[0]["case_#"];
    $id2 = $keys[1]["case_#"];
    $id3 = $keys[2]["case_#"];
    $id4 = $keys[3]["case_#"];
}

$result["txt"] = $params["url1"]."id1=".$id1."&id2=".$id2."&id3=".$id3."&id4=".$id4;

// this works fine if they select 4 records to print but it doesnt work if they select less than 4. $params["url1"] contans the page example.page.php? i want to pass the ids through the url so i can get them and then print the page 


Please help if you need to see more code let me know but i think theres a better way to do this with the loop functions of php i just dont have that much experience with PHP thanks

PHP runs on the server so only runs when the form is submitted, use javascript to disable the submit button if the selected count is not four.

Your loop doesn't really make sense. You aren't using the $idx and $val variables, so the loop will just do the exact same operation every time. You're probably trying to do something like this?

PHP Code:

$result['txt'] = $params['url1'];
foreach ($keys as $id => $val) {
   $result['txt'] .= 'id' . $id . '=' . $val . '&';
}
// Trim off the last &
rtrim($result['txt'], '&');

YES!!!!!! this is what i was looking for thank you soo much!!!! yes this was my first time using loops but this works great i just had to do a little modification to it. your code output this:

pdf_folder/page_print.php?id0=Array&id1=Array&

i didnt write the script on the page so i'm not so sure how it works but i know for each $keys[] it holds each row's value so i just need my id value ie. if i need the id they selected i would refer to it like this $val['case_#'] if i need it the first name i would do this $val['first_name'] and so on...

so i modified the code like this

PHP Code:

$result['txt'] = $params['url1']; 
foreach ($keys as $id => $val) { 
   $result['txt'] .= 'id' . $id . '=' . $val['case_#'] . '&'; 
} 
// Trim off the last & 
$fresult = rtrim($result['txt'], '&');
$result['txt'] = $fresult; 


Thanks for your help greatly appreciate it!!

You're welcome.
Oh, and you do not need that extra variable $fresult, you can replace those last two rows with this:

PHP Code:

$result['txt'] = rtrim($result['txt'], '&');
