echo multiple results from checkboxes...

[theredking]

I'm making great progress with my first real php form processing project, but I've come a little unstuck.

 

I'm trying to echo the results from a checkbox. Currently I have

<?php echo "$checkbox"; ?>

 

This works, but if multiple selections are made, it only echoes one of them. How do I fix this?

 

Thank you in anticipation!

Name them like this:

Which of the following languages do you speak?<br />
<input type='checkbox' name='lang[]' value='en' /> English<br />
<input type='checkbox' name='lang[]' value='es' /> Spanish<br />
<input type='checkbox' name='lang[]' value='fr' /> French

 

Then you can access it like $_POST['lang'] or $_GET['lang] which will be an array containing the selected languages.

Ok thanks. I have tried this, and it echoes "array" instead of the value of the checkboxes... any ideas?

doe

 

foreach ($_GET['lang'] as $value) {

echo $value;

}

 

I THINK My syntax is correct.

That because (as I said) it is an array.

 

Do

print_r($_GET['lang']);

to see and you can use d22552000's code to iterate through it (providing you send it via GET).

Ah, ok. I am sending via POST though, what options does that leave me with?

[wildteen88]

Change $_GET['lang'] to $_POST['lang'] instead for d22552000's code

yep

 

My code may not be small, but it is simple and to the point.

 

I dont understnad print -,-

Oh ok, cool thank you!

[theredking]

Ok, so I got that working, but... I have another instance of checkboxes in the same form, which I want to do the same thing for.

 

I tried to use my logic and just do:

foreach ($_POST['interest'] as $value2) {
echo "$value2 " ;

 

but that didn't work...

 

Any ideas?

What's your HTML?

[theredking]

Is this what you're asking for?

 

<input name="interest[]" type="checkbox" id="interest[]" value="Fishing" />Fishing 
<input name="interest[]" type="checkbox" id="interest[]" value="Golf" /> Golf 
<input name="interest[]" type="checkbox" id="interest[]" value="Tennis" /> Tennis 
<input name="interest[]" type="checkbox" id="interest[]" value="Swimming" /> Swimming

[d22552000]

lol it should work/

<input name="interest[]" type="checkbox" id="interest[]" value="Fishing" />Fishing 
<input name="interest[]" type="checkbox" id="interest[]" value="Golf" /> Golf 
<input name="interest[]" type="checkbox" id="interest[]" value="Tennis" /> Tennis 
<input name="interest[]" type="checkbox" id="interest[]" value="Swimming" /> Swimming

 

ids must be unique. That's not the problem though. It should work. Try print_r($_POST); on the page which your form leads to.

Ok, I don't know what I did, but I tried it again and it worked. Thanks for your time looking at this.
