blocks|key|4638388|text|还请记住，您可以将自定义索引包括到发送到服务器的数组中，如下所示|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4638389|<form+method='post'+id='userform'+action='thisform.php'>

<p>Also remember you can include custom indices to the array sent to the server like this</p>

<pre><code>&lt;form method='post' id='userform' action='thisform.php'&gt;
&lt;tr&gt;
    &lt;td&gt;Trouble Type&lt;/td&gt;
    &lt;td&gt;
    &lt;input type='checkbox' name='checkboxvar[4]' value='Option One'&gt;4&lt;br&gt;
    &lt;input type='checkbox' name='checkboxvar[6]' value='Option Two'&gt;6&lt;br&gt;
    &lt;input type='checkbox' name='checkboxvar[9]' value='Option Three'&gt;9
    &lt;/td&gt;
&lt;/tr&gt;
&lt;input type='submit' class='buttons'&gt;
&lt;/form&gt;
</code></pre>

<p>This is particularly useful when you want to use the <code>id</code> of individual objects in a server array <code>accounts</code> <em>(for instance)</em> to send data back to the server and recognize same at server </p>

<pre><code>&lt;form method='post' id='userform' action='thisform.php'&gt;
&lt;tr&gt;
    &lt;td&gt;Trouble Type&lt;/td&gt;
    &lt;td&gt;
    &lt;?php foreach($accounts as $account) { ?&gt;
        &lt;input type='checkbox' name='accounts[&lt;?php echo $account-&gt;id ?&gt;]' value='&lt;?php echo $account-&gt;name ?&gt;'&gt;
        &lt;?php echo $account-&gt;name ?&gt;
        &lt;br&gt;
    &lt;?php } ?&gt;
    &lt;/td&gt;
&lt;/tr&gt;
&lt;input type='submit' class='buttons'&gt;
&lt;/form&gt;

&lt;?php 
if (isset($_POST['accounts'])) 
{
    print_r($_POST['accounts']); 
}
?&gt;
</code></pre>


<p>I've looked around for a few examples here but a lot of them are either too advanced for my grasp of PHP or their examples are too specific to their own projects. I am currently struggling with a very basic part of a PHP form.</p>

<p>I am trying to create a form with a few checkboxes, each assigned a different value, I want these to be sent to a variable (array?) that I can echo/use later, in my case I will be sending the checked values in an email.</p>

<p>So far, I have tried a few variations, but the closest I have come to it is this...</p>

<pre><code>&lt;form method='post' id='userform' action='thisform.php'&gt;
&lt;tr&gt;
    &lt;td&gt;Trouble Type&lt;/td&gt;
    &lt;td&gt;
    &lt;input type='checkbox' name='checkboxvar' value='Option One'&gt;1&lt;br&gt;
    &lt;input type='checkbox' name='checkboxvar' value='Option Two'&gt;2&lt;br&gt;
    &lt;input type='checkbox' name='checkboxvar' value='Option Three'&gt;3
    &lt;/td&gt;
&lt;/tr&gt;
&lt;/table&gt;
&lt;input type='submit' class='buttons'&gt;
&lt;/form&gt;

&lt;?php
$checkboxvar[] = $_REQUEST['checkboxvar'];
?&gt;
</code></pre>

<p>Where I'd echo $checkboxvar[] into my email.
Am I going about this completely wrong? The other idea I had was to use a lot of if statements.</p>
