How to send an array of multiple checkboxes to email

Pett · November 2, 2016

Hey all...

Am working on a PHP form which has got radio buttons, checkbox and text-area fields. When I hit the submit button, I get all the values in my email EXCEPT the checkbox values. Kindly help me rectify the error?

PHP code

<?php

        //INITIALIZE VARIABLES
             $name = $phone = $email = $value = $package = "";
             $nameError = $phoneError = $emailError = $checkboxError = $packageError = "";


if ($_SERVER["REQUEST_METHOD"] == "POST") {   $valid = true;

    //checking name and validate using regexp
    if (empty($_POST["name"])) {

        $valid = false;
              $nameError = "Fill out this field";
    } else {
        $name = test_input($_POST["name"]);
        if (!preg_match("/^[a-zA-Z ,.-]*$/", $name)) {

            $valid = false;

            $nameError = "*Please insert Letters and white-spaces only*";
        }
    }
     
       //check phone and validate
    if (empty($_POST["phone"])) {

        $valid = false;

        $phoneError = "Please fill out this field";
    } else {
        $phone = test_input($_POST["phone"]);
        if (!preg_match("/^[0-9 ,+.-]*$/", $phone)) {

            $valid = false;

            $phoneError = "*Only numbers are allowed*";
        
        }
    }
	
          //check validity of email
    if (empty($_POST["email"])) {

        $valid = false;

        $emailError = "Please fill out this field";
    } else {
        $email = test_input($_POST["email"]);
        if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {

            $valid = false;

            $emailError = "*Invalid email address*";
           
        }
    }
	       
         // Check the values from checkbox and POST them to email
	  	if(!empty($_POST["checkbox"]))                         //check if the user has selected a CHECKBOX or NOT 
	         {
			 $checkbox =$_POST["checkbox"];                //Array of values from the checkbox
			 
			 foreach($checkbox as $value)             //loop to store and display values of individual checkboxes 
			 {echo $value;}}			               //Display selected checkbox
			else {test_input($_POST["value"]);}      //POST values to email
		  
		  
		  //check package & validate
	 if (empty($_POST["package"])) {
		 $packageError = "Select one of these options";
	} else {
		$package = test_input($_POST["package"]);}

    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);

    return $data;
	
}

Because you are reproducing exactly the same mistake from this topic http://w3schools.invisionzone.com/index.php?showtopic=56010&page=2

Yah, I referred to the query since the member had a similar problem as mine. Am an online learner of PHP in W3Schools website and envatotuts and I refer to the tuts & queries when stack. Could you help me figure the problem out?

You're not adding the checkbox values to the message body. Instead of echo $value you should append $value to the message body.

You have to properly indent your code. It's unreadable. Here are the rules:

"Level of indentation" refers to either one tab or a fixed number of spaces.
Multply the level of indentation by the number of spaces or tabs you have chosen as your indentation width and put it preceding the line of code.
The first line of your code must have no indentation, level zero.
Whenever you have an opening curly brace "{" you add one level of indentation on the lines that follow
Whenever you have a closing curly brace "}" you remove one level of indentation on that line and all the lines that follow
Closing curly braces "}" must go on their own line.

You would need to loop through each $_POST['checkbox'] value, send it to be validated/sanitized, then add each to a passed validation array, then use implode to show all values in array to message body of email.

Much appreciations for your help, I have taken into consideration your advice. But I need a helping hand concerning appending $value to the message body:

PHP

// Check the values from checkbox and POST them to email       
If (isset($_POST["checkbox"]) && !empty($_POST["checkbox"]))             
	{
		$checkbox =$_POST["checkbox"];                //Array of values from the checkbox values
			$value= implode(' , ', $checkbox);           //implode values and separate by a comma
				echo $value;
	}			               

else 
	{
		test_input($_POST["value"]);          //POST values to email
	}

Message body for the email

 $mail->Body = "Name: " . $_POST["name"] . 
	              "<br>Phone: " . $_POST["phone"] . 
			"<br>Email: " . $_POST["email"] .
			 "<br>Checkbox: " . $_POST["value"] .
			"<br>Package: " . $_POST["$package"];

HTML Form

<br> <br> What project would you like for your institution? <span class= "error"> * </span>
		           <br> <br> <input type="checkbox" class="input" name="checkbox[]" value="Graphics Design"> Graphics Design (Book, Posters,   Flyers, Banners, Magazines, T-Shirts) <br>
                   <input type="checkbox" class="input" name="checkbox[]" value="Logo Design" > Professional logo Design <br>
                   <input type="checkbox" class="input" name="checkbox" value="Branding" > Branding

Like I explained to you and the topic you borrowed this from, you first need to loop through each checkbox value first to validate and santize, before inserting in email message body.

Pett · November 3, 2016

Here's what I've got:

// Check the values from checkbox and POST them to email       
If (isset($_POST["checkbox"]) && !empty($_POST["checkbox"]))             
	{
		$checkbox = array("Graphics Design", "Logo Design","Branding");               //loop through each checkbox value
			$value= implode(' , ', $checkbox);           //implode values and separate by a comma
	}			               

else 
	{
		test_input($_POST["value"]);          //POST values to email
	}

Would you mind explaining using an example?

You are not looping, you are not checking values from $_POST["checkbox"] but! for some reason I do not know why? have decided to check a array of ALL checkbox values?
