checkbox array question

[kpowning]

I have a form where im getting members images from the database. I have 3 submit buttons.

1) Delete Image
2) Remake Thumb
3) Set Default

How can I show all the members images from the database and show a radio button for all images. Allow the member to select one image and then click one of the three buttons above and perform that operation for that specific image?

Thanks for any input...

your buttons are probably all going to be submit buttons. The trick then is in constructing your radio buttons properly. Since each image has a unique name or id, you should probably build them like this. Assume that $image_id contains a unique id (file name or database id) for each image:

<input name="image" value="<?=$image_id ?>">

Each image, when output in the html, will have a different value for $image_id so each radio button will have a different value. In your form handling code, you'll be able to look at $_POST['image'] to see which image was chosen. The action you perform will depend on which submit button they clicked.

thanks for the response. But what if I allow them to give a name per image as well.. I appreciate your help.

the trick is to have all the radio buttons have the same name (such as 'image') and have each radio button's value correspond to the image that it represents. I'm guessing that you output all the images in a loop:

echo '<form method="post">';
foreach($images as $image_name) {
    echo '<input type="radio" name="image" value="' . $image_name . '">' . $image_name . '<br>';
}
echo '<input type="submit" name="submit" value="delete image">';
echo '<input type="submit" name="submit" value="remake thumb">';
echo '<input type="submit" name="submit" value="set default">';
echo '</form>';

sneakyimp - I can do this already, but the problem is if they have 7 images thats alot of buttons being shown on the one page. I was hoping to make it so that there are three permanent buttons and each image has a checkbox in order to select that image and then click the button to form that operation for that specific image.

Thanks for your help!

That loop i created will only have 3 buttons. You should pay more attention.

ok i agree.. 🙂 if i needed to pass another line of code per image should i just use the same layout as field "image" ?

I'm not sure what you mean. Maybe you should read the manual about [man]foreach[/man].
