如何阅读,如果一个复选框被选中在PHP?


当前回答

$is_checked = isset($_POST['your_checkbox_name']) &&
              $_POST['your_checkbox_name'] == 'on';

短路计算将会注意,这样您就不会在your_checkbox_name未提交时访问它。

如果你的HTML页面是这样的:

<input type="checkbox" name="test" value="value1">

提交表单后,您可以检查它:

isset($_POST['test'])

or

if ($_POST['test'] == 'value1') ...
<?php

if(isset($_POST['nameCheckbox'])){
    $_SESSION['fr_nameCheckbox'] = true;
}

?>

<input type="checkbox" name="nameCheckbox" 

<?php 

if(isset($_SESSION['fr_nameCheckbox'])){
    echo 'checked'; 
    unset($_SESSION['fr_nameCheckbox']);
} 

?>

filter_input(INPUT_POST, 'checkbox_name', FILTER_DEFAULT, FILTER_FORCE_ARRAY)

我已经把它固定成一个带有复选框的PHP表单

$categories = get_terms(['taxonomy' => 'product_cat', 'hide_empty' => false]); Foreach ($categories为$ categororie) { Echo "<input type="checkbox" value="$ categororie ->term_taxonomy_id" name="catselected[]"> $ categororie ->slug"; }

这样我把它添加到Woocommerce表。 wp_set_post_terms($product_id, $_POST['catselected'], 'product_cat');

<?php

  if (isset($_POST['add'])) {

    $nama      = $_POST['name'];
    $subscribe = isset($_POST['subscribe']) ? $_POST['subscribe'] : "Not Checked";

    echo "Name: {$nama} <br />";
    echo "Subscribe: {$subscribe}";

    echo "<hr />";   

  }

?>

<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" method="POST" >

  <input type="text" name="name" /> <br />
  <input type="checkbox" name="subscribe" value="news" /> News <br />

  <input type="submit" name="add" value="Save" />

</form>
