在使用PHP提交表单后，如何检查复选框？

Question

I'm trying to get a value from post array then store it in a variable then use the value to keep the checkbox selected. Here's what I'm trying:

I have this line above the foreach:

    <input type='checkbox' name='$plyrMtchResult 'value=''>$plyrMtchResult</input>  //This line works fine

 //then when I submit the form the foreach loop runs here.

  foreach($_POST as $value => $key)
        {

                $post_Value= str_replace("_", " ", $value);

                "<input type='checkbox' name='$post_Value' value='post_valuebValue' checked='checked'>$post_valuebValue</input>";

        }

My issue seems similar to what I found here but mine is not working.

How can I keep the checkbox checked after I submit the form.

Answer 1

<input type='checkbox' name='$post_Value'     value='post_valuebValue'    checked='checked'>$post_valuebValue</input>

I would do something like this please forgive any syntax errors in doing this on my phone

<input type='checkbox' name='$post_Value' value='post_valuebValue' <?pho if ($postvalue = checked){echo 'checked='checked'}?>'>$post_valuebValue</input>";

Echo checked html into field to keep it checked
