    text
    copied!<p>would be grateful for some help on this:</p> <p>I have a set of checkboxes where users are encouraged to select at least one option. I would like to store all of these options in a single variable using PHP and then in turn attach this variable on to the end of an email body to send to the site host using email. However, I can only seem to retrieve the last option that the user selects. I have tried using the array syntax (e.g. name="instrument[]") but I cannot seem to find a way to retrieve the values from this array. I have used the 'implode' method to store the post value but I keep on receiving an error message, saying "Warning: implode(): Invalid arguments passed in C:\xampp\htdocs\academy\contact-process.php on line 8".</p> <p>My code is below:</p> <p>Contact.html</p> <pre><code>&lt;tr&gt; &lt;td&gt; &lt;label id="checkbox"&gt;Piano&lt;/label&gt; &lt;input id="piano" type="checkbox" name="instrument[]" value="Piano" class="required" title="Please check at least one option."&gt; &lt;/td&gt; &lt;td&gt; &lt;label id="checkbox"&gt;Flute&lt;/label&gt; &lt;input id="flute" type="checkbox" name="instrument[]" value="Flute"&gt; &lt;/td&gt; &lt;td&gt; &lt;label id="checkbox"&gt;Singing&lt;/label&gt; &lt;input id="singing" type="checkbox" name="instrument[]" value="Singing"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; &lt;label id="checkbox"&gt;Violin&lt;/label&gt; &lt;input id="violin" type="checkbox" name="instrument[]" value="Violin"&gt; &lt;/td&gt; </code></pre> <p>Contact-process.php:</p> <pre><code>&lt;pre&gt;&lt;?php $title = $_POST["title"]; $forname = $_POST["firstname"]; $surname = $_POST["lastname"]; $phone = $_POST["phone"]; $instrument = implode(' ', $_POST["instrument"]); $hear = $_POST["method"]; $enrole = $_POST["child"]; $dob = $_POST["date"]; $message = $_POST["enquiry"]; $email_body = ""; $email_body = $email_body . "Title: " . $title . "\n"; $email_body = $email_body . "Forname: " . $forname . "\n"; $email_body = $email_body . "Surname: " . $surname . "\n"; $email_body = $email_body . "Telephone Number: " . $phone . "\n"; $email_body = $email_body . "Heard About You From: " . $hear . "\n"; $email_body = $email_body . "Interested In Learning: " . $instrument . "\n"; $email_body = $email_body . "Would Like To Enrole A(n): " . $enrole . "\n"; $email_body = $email_body . "Child's Date of Birth: " . $dob . "\n"; $email_body = $email_body . "Message: " . $message; echo $email_body; ?&gt;&lt;/pre&gt; </code></pre> <p>At the moment this generates the error message as described above.</p> <p>Anyone know a solution?</p> <p>Thanks so much for any replies!!</p> <p>Robert.</p>
