title: Send Multiple Text Fields in Array in PHP
body: <p>I have the following code in my file:</p>
  
  <pre><code>&lt;table width="100%" class="friends"&gt;
  &lt;tr&gt;
      &lt;th width="50%"&gt;Friends Name&lt;/th&gt;
      &lt;th&gt;Friends Email&lt;/th&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input type="text" name="friendname[]" id="friendname[]" class="validate[minSize[4]]" min="4" placeholder="John &amp;amp; Jane Doe" style="width:80%;" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;input type="text" name="friendemail[]" id="friendemail[]" class="validate[custom[email]]" min="4" placeholder="jandjdoe@example.com" style="width:80%;" /&gt;&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p></p>
  
  <p>And the following as my PHP Code:</p>
  
  <pre><code>if(!empty($_POST['friendname']) &amp;&amp; !empty($_POST['friendemail']) &amp;&amp; is_array($_POST['friendname']) &amp;&amp; is_array($_POST['friendemail']) &amp;&amp; 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; $i &lt; count($name_array); $i++) {
      $name = $name_array[$i];
      $email = $name_array[$i];
  }
  </code></pre>
  
  <p>However my code isn't echoing anything.</p>
  
  <p>I got the code for the above from <a href="https://stackoverflow.com/questions/18156505/insert-multiple-fields-using-foreach-loop">insert multiple fields using foreach loop</a></p>
  
  <p>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? :)</p>
