您必须添加“禁用”属性。到html-element＆＃39;输入＆＃39;。要根据条件做到这一点 - 在你的情况下 - 它会是这样的。

<?php
// inside your while-loop

$disabled = '';  // default
if ($partner == 'No') { // check the double == here!
    $disabled = "disabled";
}
?>

// then add that string-var to the html-element
<input type="checkbox" name="checkPartner" <?php echo $disabled ?>/>

根据表中的值禁用或启用复选框
