[RESOLVED] What to ad to get the proper results from checkboxes?

[Josefina]

I'll try to make sense despite the fact that my english is bad ...

I'm setting up an online survey and I want to add checkboxes to the form. I made it work just fine with radio buttons - the proper results is presented in the e-mail that is sent.

I get results from the checkboxes too, but only the last one of checked checkboxes is presented as checked in the e-mail. No matter how many checkboxes are checked in the form, in the results it seems like only one is checked.

Any clever ideas on what to change or add to make this work?

Here's my xhtml:

<form method="post" action="sendmail.php" style="margin-top: 13px; margin-bottom: 0px;">


<br />
<h2>Question 1</h2>
<br />
<input type="radio" name="education" value="A" /> No
<br />
<input type="radio" name="education" value="B"/> Yes, some courses
<br />
<input type="radio" name="education" value="C"/> Yes, several years


<br />
<br />
<h2>Question 2</h2>
<br />
<input type="checkbox" name="media" value="A" /> Newspaper
<br />
<input type="checkbox" name="media" value="B" /> Website
<br />
<input type="checkbox" name="media" value="C" /> E-magazine
<br />
<input type="checkbox" name="media" value="D" /> E-mail
<br />
<input type="checkbox" name="media" value="E" /> TV
<br />
<br />

<br />
<br />
<h2>Question 3</h2>
<br />
<input type="checkbox" name="decisions" value="A" /> How
<br />
<input type="checkbox" name="decisions" value="B" /> Why
<br />
<input type="checkbox" name="decisions" value="C" /> When
<br />
<input type="checkbox" name="decisions" value="D" /> Where
<br />
<input type="checkbox" name="decisions" value="E" /> To whom
<br />
<br />

<input class="button" type="submit" value="Send" style="font-family: Arial, sans-serif; font-size: 12px;"/>
<input class="button" type="reset" value="Reset" style="font-family: Arial, sans-serif; font-size: 12px; margin-left: 3px;"/>
</form>

And my php:

<?php


// Get all $_POST variables
foreach($_POST as $var => $val)
{
	${$var} = $val;
}

// Set up the email body
$body_body .=  "ANSWERS:\n";
$body_body .=  "    Education-------------| ".$education."\n";
$body_body .=  "    Choice of media-------| ".$media."\n";
$body_body .=  "    Decisions-------------| ".$decisions."\n";


$to = 'Josefina <[e-mail]>';
$subject = 'Survey';
$body = $body_body;

mail($to, $subject, $body);

/*
echo '<div style="white-space: pre">';
print_r(str_replace("\n", "<br />",$body));
echo '</div>';
*/
?>

Getting Check box values using array in PHP
http://www.plus2net.com/php_tutorial/array_checkbox.php
and here is another tutorial
http://www.kavoir.com/2009/01/php-checkbox-array-in-form-handling-multiple-checkbox-values-in-an-array.html

So, what you should use is name="media[]" in each option
which will return an array in $_POST

<input type="checkbox" name="media[]" value="A" /> Newspaper

[djjjozsi]

how to check if a checkbox has checked:

<input type="checkbox" name="media" value="A" /> Newspaper

if(isset($_POST["media"]))
$body.="Media has selected!";

On multiple checkboxes, you have to add array variable name:

<input type="checkbox" name="media[]" value="Newspaper" /> Newspaper
<input type="checkbox" name="media[]" value="Truck" /> Truck

How to get the results array?

if(isset($_POST["media"]))
$body.="Selected media" . implode("," , $_POST["media"]);
else
$body.="media is empty" ;

Maybe I should have posted my thread in the noob-category ...

When I use djjjozsi's solution the results get presented as "Array" in the e-mail. The same thing happends when I use the method in the tutorials halojoy referred to ...

This is my new xhtml:

<form method="post" action="sendmail.php" style="margin-top: 13px; margin-bottom: 0px;">


<br />
<h2>Question 1</h2>
<br />
<input type="radio" name="education" value="A" /> No
<br />
<input type="radio" name="education" value="B"/> Yes, some courses
<br />
<input type="radio" name="education" value="C"/> Yes, several years


<br />
<br />
<h2>Question 2</h2>
<br />
<input type="checkbox" name="media[]" value="A" /> Newspaper
<br />
<input type="checkbox" name="media[]" value="B" /> Website
<br />
<input type="checkbox" name="media[]" value="C" /> E-magazine
<br />
<input type="checkbox" name="media[]" value="D" /> E-mail
<br />
<input type="checkbox" name="media[]" value="E" /> TV
<br />
<br />


<input class="button" type="submit" value="Send" style="font-family: Arial, sans-serif; font-size: 12px;"/>
<input class="button" type="reset" value="Reset" style="font-family: Arial, sans-serif; font-size: 12px; margin-left: 3px;"/>
</form>

and the two verions of php I've tried:

<?php


// Get all $_POST variables
foreach($_POST as $var => $val)
{
	${$var} = $val;
}

if(isset($_POST["media"]))
$body.="Selected media" . implode("," , $_POST["media"]);
else
$body.="media is empty" ;

// Set up the email body
$body_body .=  "ANSWERS:\n";
$body_body .=  "    Education-------------| ".$education."\n";
$body_body .=  "    Choice of media-------| ".$media."\n";
$body_body .=  "    Decisions-------------| ".$decisions."\n";


$to = 'Josefina <[e-mail]>';
$subject = 'Survey';
$body = $body_body;

mail($to, $subject, $body);

/*
echo '<div style="white-space: pre">';
print_r(str_replace("\n", "<br />",$body));
echo '</div>';
*/
?>

<?php


// Get all $_POST variables
foreach($_POST as $var => $val)
{
	${$var} = $val;
}

$media=$_POST['media'];

while (list ($key,$val) = @each ($media)) {
echo "$val,";
} 

// Set up the email body
$body_body .=  "ANSWERS:\n";
$body_body .=  "    Education-------------| ".$education."\n";
$body_body .=  "    Choice of media-------| ".$media."\n";
$body_body .=  "    Decisions-------------| ".$decisions."\n";


$to = 'Josefina <[e-mail]>';
$subject = 'Survey';
$body = $body_body;

mail($to, $subject, $body);

/*
echo '<div style="white-space: pre">';
print_r(str_replace("\n", "<br />",$body));
echo '</div>';
*/
?>

In both cases my e-mail says:
Education--------------| B
Choice of media------| Array

What am i doing wrong? (Probably all of it 🙂

[djjjozsi]

then forget the copy paste programming. All my suggestions had example variable names, such as $body...

you did not add the $body into your real message body.

[Josefina]

Ah, I fixed it by changing $body to $media! Works fine now!

Thanks for your help and sorry for my stupidity ...

[djjjozsi]

Your welcome 🙂

... sorry for my stupidity ...

You don't need to say that 🙂

If think you find the answer now, don't forget to set this thread as resolved, please.
