Course Checkbox

Hi again, trust you are all well.

My query is about holding the check / uncheck value for a checkbox for the assignment.

Below is an extract from the tutorial example:-

Language: PHP
if (isset($_POST[';Submit1';])) {
 
if (isset($_POST[';ch1';])) {
$ch1 = $_POST[';ch1';];
 
if ($ch1 = = ';net';) {
$ch1 = ';checked';;
}
}

My code looks like the following:-

Language: PHP
$SQL="SELECT * FROM course";
	$result=mysql_query($SQL);
	while($db_field=mysql_fetch_assoc($result)){
 
		if (isset($_POST[';ch';.$db_field[';cid';]])){
 
			$check_course[$db_field[';cid';]] = ';checked';;
		}
	}

The isset() lines of code ito the checkbox refer to my query. Essentially I can't read in the value. Get an undefined index error. Maybe someone can see the obvious mistake. I hope so.

Alternatively does anyone have a few suggestions / tips when using checkboxes.

Thanks in advance.

Undefined index is a notice, not an error. Do a search on it in the forums - it has been addressed.

I don't get the use of the sql query here - there always will be a result? You need to add a where statement, an if a row exists then present the check box as either selected or not. Except if I misunderstand what you are truing to achieve...

This is what I did with my checkbox

Language: PHP
		<td></td><td><label>Share Info:</label><input type="checkbox" name="studSHARE" . <?php echo ($studShare == ';1';)?';checked';:';';?> . tabindex="19"></td>

The value 1 comes from my database where, if it is checked the value '1' gets stored in the database.

Hi all,

Thanks to everyone for their comments. Found a solution. Yay!!!!

Essentially I checked to see which checkbox was checked using isset() function.

Then set that checkbox to checked.

Used arrays. Below is the code used.

Language: PHP
if (isset($_POST[$check_id[$i]])){
$check_course[$i] = ';checked';;
.......
}

Quite simple in the end.

cheers

Works great!!
