post without form ?

Threaded View

I have this list of  logs stored in a MySQL DB.
I display them in a list and next to each log I have a del view LINK

I want to add Checkboxes next to each log and keep del and view links as

Then you can select all the logs you want to delete, hit a delete Link and
send the variables in a script...
Can you do that without having a form ?

Can you have a checkbox without having a form ?

It sounds a bit awkward but I am just wandering

<li><a href="transaction.php?contCat=<? echo $contCat
?>&action=delete&contSubCat=<? echo $contSubCat ?>&content_id=<?php echo
$row['backup_id']; ?>"onClick="return formConfirm('del')">Del</a><input
name="<?php echo $row['backup_id']; ?>" type="checkbox" value="1">

Re: post without form ?

Nope -- without a <form> tag the checkbox values won't make it to the
next page.

Not one that will do anything, unless you also want to use JavaScript. Of
course, that brings on a whole pile of other issues.

Why would you not want to have a form?

Unless next_page.php generates PHP, the script with this include will
only get HTML.

How Can You get the checkbox Values

Ok considering wi have the above code tha loops and lists a Number of DB
how can we assign a checkbox in each of them and then retrieve each
checkboxs' value  in order to delete the appropriate record when the form is
submited ?

THanks !!!

Re: How Can You get the checkbox Values

Ok try something like this (example code... i tried to comment in it as
much as possible):

for this example.. logs table structure:
id (primary, auto-increment)



//connect to db

if(!isset($_POST['submit'])) {
//form isn't submitted

echo "<b>Logs</b><br><br>";

echo "<form action=\"\" method=\"post\">";

$query = "SELECT * FROM logs";
$result = mysql_query($query);
while($row = mysql_fetch_array($result)) {
    $id = $row['id'];
    $description = $row['description'];
    echo "Log: $description <input type=\"checkbox\" name=\"log_$id\"
//get all log values, and present checkbox
//NOTE: checkbox values are prefixed with 'log_', explained later..

echo "<input type=\"submit\" name=\"submit\" value=\"Delete\">";
//input button

} else {

    foreach ($_POST as $key => $value) {
        if(strstr($key, 'log_')){
        //if the value contains log_ then its used
            if($value == '1'){
                $id = str_replace("log_", "", $key);
                //log_ prefix is removed to get the id
                $query = "DELETE FROM logs WHERE id='$id'";
                mysql_query($query) or
                  die (mysql_error());



echo "<b>Done</b>";




ok basics behind the script...

since theres an unknown number of form values the following is used:

foreach ($_POST as $key => $value) {

....which loops through all the form elements and their values.
However this can cause a problems, because other form elements will be
picked up other than the checkboxes, such as the input button. THIS is
the reason that i prefixed all checkboxs with 'log_', so it can later
be checked.

i hope this is the kind of thing you are after ;)
