[PHP] php and checkboxes.
Hi all I have a table that is populated from a database which gets the IDs of the records from a php array.Every row in the table has a checkbox next to the actual record, what I want to do is to allow the user to select the records they want to remove by clicking the checkbox(es) and then click a button to submit the form. so how do I remove these records? do I: -do I do an array_diff and then just select the records that are remaining? this to me seems the most logical. tia -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] php and checkboxes.
Simple:
foreach($_POST['del_checkboxes'] as $id) {
$sql=delete from table where id='$id';
}
Checkboxes are created using
input name=del_checkboxes value=?= $id ?

Hi Marek,
I dont actually want to delete the record from the database, perhaps I wasnt
very clear in my explanation, but I just need to remove that entry from the
table.
kinda like when deleting mail from your web email account like hotmail.

To remove a record is to delete a row. Same thing. When you say
entry, do you mean record or row? Or do you mean something else?
If you want to change one or more columns of a row (this can also
be stated as one or more fields of a record), use the SQL command
UPDATE table SET col1=expr1,col1=expr2,... WHERE ID=id_expr.

Same idea...
input type=checkbox name=remove[] value=xx
Where xx is the ID of that entry/row.
Then, to select whatever is in the table, minus whatever was selected...
$list = implode(',',$_POST['remove']);
$query = SELECT * FROM Table WHERE id NOT IN ($list);
If you want this list to propagate each time things are selected, then
you'll have to remember what's been selected using the session or hidden
elements.

[PHP] php and checkboxes
Hi all, I have a table that gets populated from records of a DB. every row in the table has a checkbox and the items desc. I want the user to select the items they want and then they click on a link which registers the items they've selected in a session variable. Firstly I am not sure if this can be done on that same page or on the page to which the link calls. IE: if php can determine which checkboxes have been selected. All the checkboxes are all part of an array. this is the way it should work: 1. the user selects the items they want 2. then clicks a link to another page 3. this page then displays what was selected 4. this info must be sent in a session variable. 5. must not use a submit button as I want the info to be saved in session variable. I hope that this makes sense. TIA -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'd personally go for the form solution since the URL will be ugly. 3. this page then displays what was selected Form submits to the same page in which it is presented. 4. this info must be sent in a session variable. Why? Set up the session variable using the data submitted by the form. 5. must not use a submit button as I want the info to be saved in session variable. Once again why? Sure I can see not using a submit button, but I don't see how that relates to the info being saved in a session variable. I hope that this makes sense.
