Advice on approach for a script

[timski72]

Hi guys,

I have a script that does different tasks depending on which button they press on a form.

I set the buttons on the form as follows

<td align=\"left\">
<form action=\"$_SERVER[PHP_SELF]\" method=\"post\">
    			<input type=\"hidden\" name=\"VideoToDelete\" value=\" $row[0] \"/>
    			<input type=\"submit\" name=\"button\" id=\"delete\" value=\"delete\"/>
    			</form>
      		</td>
    		<td align=\"left\">
    			<form action=\"$_SERVER[PHP_SELF]\" method=\"post\">
    			<input type=\"hidden\" name=\"VideoToEdit\" value=\" $row[0] \"/>
    			<input type=\"submit\" name=\"button\" id=\"edit\" value=\"edit\"/>
    			</form>
      		</td>

I've used a hidden element which holds the value of the video I want to perform an action on, e.g. edit, or delete and a submit element called button with a value of edit or delete which I then use in a swtich in a script as follows:

   switch (@$_POST['button']) {
                 case "edit":
        // edit code
	break;
	case "delete":
// delete code
break;
		

That seems to be working fine. Now I want to use one of the columns in my table that holds a small thumb nail (image) as a button. I was hoping the same approach would work. I set the thumbnail image up as follows:

<td align=\"left\">
				<form action=\"$_SERVER[PHP_SELF]\" method=\"post\">
				<input type=\"hidden\" name=\"thumbToUpload\" value=\" $row[0] \"/>
				<input type=\"image\" src=\"$Thumb\" height=\"30\" width=\"40\" border=\"0\" name=\"button\" value=\"submit\" />
			</form>
			</td>

and added a new value to the switches

   switch (@$_POST['button']) {
                 case "edit":
        // edit code
	break;
	case "delete":
// delete code
break;
case "submit":
// submit code
break;
		

but it doesn't. Any tips would be very welcome.

I think some browsers only transmit the x and y coordinates clicked when you use a type="image". You might be better off using a button element with type="submit" and wrap it around an image tag (with a bit of CSS as needed to make things render just right).

Thanks for the tip.

To eliminate errors in my dodgy html I tried the button tag without wrapping it around an img tab first. I tried the folllowing but without success.

	<td align=\"left\">
				<form action=\"$_SERVER[PHP_SELF]\" method=\"post\">
				<input type=\"hidden\" name=\"thumbToUpload\" value=\" $row[0] \"/>
				<button type=\"submit\" name=\"button\" id=\"button\"value=\"submit\" </button> 
			</form>
			</td>

Is that what you had in mind?

Thanks,
Tim.

Looks like you omitted the closing ">" on the <button tag?

[timski72]

Ah yes thanks I had missed the ">" of the button tag but even with it I am still not getting any joy.

Best I can suggest is to try doing a print_r($_POST) to see what is actually making it through to your script, and go from there. (You'll probably want to wrap that call in <pre> tags to make it easier to read.)
