[PHP-DB] Re: Need help with delete and modify functions on a form.
Checkbox form element is easy to applied in php if you have a script like this : form input type=checkbox name=check1 value=someValuenbsp;Some Value /form Then to get the value of checkbox you can do this : ?php // print the value of checkbox echo $_POST[check1]; ? You can also use an array : form input type=checkbox name=check[] value=someValue1nbsp;Some Value 1 input type=checkbox name=check[] value=someValue2nbsp;Some Value 2 input type=checkbox name=check[] value=someValue3nbsp;Some Value 3 /form to get the the third value from the form you can do like this : ?php echo $_POST[check][2]; ?

Bastien Thanks Bastien, that would do the job, ill study it to adapt it to my needs. Another thing, i have some flash buttons, (im ussing dreamweaver), so once the records are displayed, user can filter the info lets say choosing the lastname filed, as its a precompiled button i only can specify a link. I saw once that with php you can specify pure code on the link funcion is there any chance to specify in the link section the filter code? like: SELECT * from mydatabase where lastname = 'john'??? i think it was a way but i can´t find it now?? Also, do you have any experience with checkbox on a form, i mean some tut?? Thanks.

-Original Message- From: Arie Nugraha [mailto:[EMAIL PROTECTED] You can also use an array : form input type=checkbox name=check[] value=someValue1nbsp;Some Value 1 input type=checkbox name=check[] value=someValue2nbsp;Some Value 2 input type=checkbox name=check[] value=someValue3nbsp;Some Value 3 /form to get the the third value from the form you can do like this : ?php echo $_POST[check][2]; ? Good basic examples, two notes though - 1) form method=post (blindingly obvious to most, but might confuse some) 2) the name/value pair will only be POSTed if it's checked, so that would only work if the first two were checked. Some people like to pair all their checkboxes with a hidden of the same name, the hiddens value will be sent if the checkbox isn't checked. Personally, I prefer having an actual unique name for the checkbox when you need to check a specific one. If you don't need to check if 'the third one' is set, but you're just getting - for e.g. - a list of pizza toppings, then the order doesn't matter and [] works fine. Otherwise (if it does), give it a unique name: input type=checkbox name=check[0] value=someValue1nbsp;Some Value 1 input type=checkbox name=check[1] value=someValue2nbsp;Some Value 2 input type=checkbox name=check[2] value=someValue3nbsp;Some Value 3 (although a little more unique would be clearer :) ) cheers, - Martin Norland, Sys Admin / Database / Web Developer, International Outreach x3257 The opinion(s) contained within this email do not necessarily represent those of St. Jude Children's Research Hospital. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

?php echo $_POST[check][2]; ? 2) the name/value pair will only be POSTed if it's checked, so that would only work if the first two were checked. Some people like to pair all their checkboxes with a hidden of the same name, the hiddens value will be sent if the checkbox isn't checked. The following method worked well for me using the ternary conditional operator (?:): $step = (isset($_POST['step'])) ? $_POST['step'] : NULL; isset checks to see if a field named 'step' was received thru a POST operation. The statement creates a variable named $step. If the field 'step' was passed, it sets $step to it's value. If the field 'step' was not passed, it sets $step to NULL (you could set it to anything you wanted). Be sure you keep it straight whether the field you are looking for was passed by a POST or a GET. If the field is appended on the URL, use $_GET['fieldname']. It is possible to receive formfields through a POST operation and fields on the URL (use GET) at the same time.
