Send Multiple Text Fields in Array in PHP

Question

I have the following code in my file:

<table width="100%" class="friends">
<tr>
    <th width="50%">Friends Name</th>
    <th>Friends Email</th>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>
<tr>
    <td><input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp; Jane Doe" style="width:80%;" /></td>
    <td><input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="[email protected]" style="width:80%;" /></td>
</tr>

And the following as my PHP Code:

if(!empty($_POST['friendname']) && !empty($_POST['friendemail']) && is_array($_POST['friendname']) && is_array($_POST['friendemail']) && count($_POST['friendname']) === count($_POST['friendemail'])) {
    $err[] = "Please enter in your friend's details.";
}

$name_array = $_POST['friendname'];
$email_array = $_POST['friendemail'];
for ($i = 0; $i < count($name_array); $i++) {
    $name = $name_array[$i];
    $email = $name_array[$i];
}

However my code isn't echoing anything.

I got the code for the above from insert multiple fields using foreach loop

I have other fields inside my form and they work fine, but for some reason these don't. Does anyone know of a way to do what I'm looking for based on the code above? :)

foreach (array_combine($_POST['friendname'], $_POST['friendemail']) as $name => $email) {
 echo $name . " - " . $email . "<br />";
}

thanks @BeatAlex that's really helpful! But unfortunately my code shows the arrays as being empty. I put echo $_POST['friendname'];echo $_POST['friendemail'];exit(); at the top of my submit code and it just came back ArrayArray

You can't "echo" an array in PHP. Put var_dump($_POST['friendname']);var_dump($_POST['friendemail']);exit(); on top of your page

@nahime sorry you are correct. I changed it to

echo '<pre>';var_dump($_POST['friendname']);echo '</pre>';echo '<pre>';var_dump($_POST['friendemail']);echo '</pre>';exit();

and that gave me results, but I use

if(!empty($_POST['friendname']) && !empty($_POST['friendemail']) && is_array($_POST['friendname']) && is_array($_POST['friendemail']) && count($_POST['friendname']) === count($_POST['friendemail'])) {

for validation and that isn't giving me anything. Any ideas?

What does your var_dump return?

Vincenzo Petrucci Over a year ago

You're checking that both have same length. Look at the var_dump to see if that's true. BTW, have you tried @BeatAlex solution without validating before?
