RE: Identify which button is clicked

lsh

Hi there. I have 4 buttons on the same form- add, edit, delete and cancel button. When user select the course he wanted from the list box, the values are displayed in the textboxes. When user clicked on add button, i need to insert some records which the user has typed into the database. And if the user clicked on the edit button, i would need to update the new infomation that the user has typed into the database. So, I would like to ask how can i idenfy which button the user has clicked on so as to perform certain actions?

I tried using hidden values, but it didnt work.

Below is my code:

<form method = "post" action = "course.php">
<input type = "button" value="add" name="Add">
<input type = "button" value="edit" name="Edit">
<input type = "button" value="delete" name="Delete">
<input type = "submit" value="cancel" name="Cancel">

<input type = "hidden" value="add" name="Add">
<input type = "hidden" value="edit" name="Edit">
<input type = "hidden" value="delete" name="Delete">
<input type = "hidden" value="cancel" name="Cancel">

if ($checkStatus = $POST_['add']){
 $insertCourse = "insert into Course (name, country, speaker) values ($name, $country,$speaker)";

$exeInsertCourse = mysql_query($insertCourse);
}

if ($checkStatus = $POST_['edit']){
 $editCourse = "update Course set (name = $name, country=$country, speaker=$speaker)";

$exeEditCourse = mysql_query($editCourse);
}

if ($checkStatus = $POST_['delete']){
 $deleteCourse = "delete from Course where c_id = $c_id";

$exeDeleteCourse = mysql_query($DeleteCourse);
}

Can anyone help me? Thanks.

Name the buttons, then use them as you would use normal incoming variables from forms.

if a button is named "edit" and it is pressed then you can check for it on the next page using isset()

so
<input name="edit" type="submit" value="Edit">
<input name="add" type="submit" value="Add">

if( isset($_POST/GET['edit']) ) {
   echo "EDIT has been pressed";
}elseif( isset($_POST/GET['add']) ) {
   echo "ADD has been pressed";
}
