重力形式-如何在标签元素内移动单选输入

Question

我正在将WordPress Gravity Forms与Quiz Addon一起使用，并且我想编辑测验答案的单选输入的HTML。

这是测验答案的每个li元素当前正在呈现的重力形式：

<li class="gchoice_3_1_1">
    <input name="input_1" type="radio" value="gquiz1c4448d0c" checked="checked" id="choice_3_1_1" tabindex="2">
    <label for="choice_3_1_1" id="label_3_1_1" class="gquiz-correct-choice">Example label text
        <img class="gquiz-indicator" src="https://www.example.com/wp-content/plugins/gravityformsquiz-master/images/tick.png" alt="Correct response">
    </label>
</li>

这是我想要实现的（将input元素移到label字段中：]

<li class="gchoice_3_1_1">
    <label for="choice_3_1_1" id="label_3_1_1" class="gquiz-correct-choice">Example label text
        <input name="input_1" type="radio" value="gquiz1c4448d0c" checked="checked" id="choice_3_1_1" tabindex="2">
        <img class="gquiz-indicator" src="https://www.example.com/wp-content/plugins/gravityformsquiz-master/images/tick.png" alt="Correct response">
    </label>
</li>

这是我在子主题functions.php中尝试使用的PHP函数，以实现它：

// move radio input inside label
add_filter("gform_field_choices", "radio_input_inside_label", 10, 2);
function radio_input_inside_label($choices, $field){
    if($field["type"] != "radio")
        return $choices;

    $choices = "";

    if(is_array($field["choices"])){
        $choice_id = 0;
        $count = 1;

        $logic_event = !empty($field["conditionalLogicFields"]) ? "onclick='gf_apply_rules(" . $field["formId"] . "," . GFCommon::json_encode($field["conditionalLogicFields"]) . ");'" : "";

        foreach($field["choices"] as $choice){
            $id = $field["id"] . '_' . $choice_id++;
            $field_value = !empty($choice["value"]) || rgar($field, "enableChoiceValue") ? $choice["value"] : $choice["text"];
            $checked = rgar($choice,"isSelected") ? "checked='checked'" : "";
            $tabindex = GFCommon::get_tabindex();

            $input = sprintf("<input name='input_%d' type='radio' value='%s' %s id='choice_%s' $tabindex $logic_event />", $field["id"], esc_attr($field_value), $checked, $id);
            $choices .= sprintf("<li class='gchoice_$id'><label for='choice_%s'>%s %s</label></li>", $id, $choice["text"], $input);

            $count++;
        }

    }

    return $choices;
}

此功能适用于标准无线电输入，它将input移到label内。但不适用于测验无线电输入。

你能看到什么问题吗？

我使用了错误的字段类型选择器。

如果要在正常重力的单选按钮的标签元素内移动单选输入，那么此代码将起作用：

// Gravity Forms Quiz - move radio input inside label
add_filter("gform_field_choices", "radio_input_inside_label", 10, 2);
function radio_input_inside_label($choices, $field){
    if($field["type"] != "radio")
        return $choices;

    $choices = "";

    if(is_array($field["choices"])){
        $choice_id = 0;
        $count = 1;

        $logic_event = !empty($field["conditionalLogicFields"]) ? "onclick='gf_apply_rules(" . $field["formId"] . "," . GFCommon::json_encode($field["conditionalLogicFields"]) . ");'" : "";

        foreach($field["choices"] as $choice){
            $id = $field["id"] . '_' . $choice_id++;
            $field_value = !empty($choice["value"]) || rgar($field, "enableChoiceValue") ? $choice["value"] : $choice["text"];
            $checked = rgar($choice,"isSelected") ? "checked='checked'" : "";
            $tabindex = GFCommon::get_tabindex();

            $input = sprintf("<input name='input_%d' type='radio' value='%s' %s id='choice_%s' $tabindex $logic_event />", $field["id"], esc_attr($field_value), $checked, $id);
            $choices .= sprintf("<li class='gchoice_$id'><label for='choice_%s'>%s %s</label></li>", $id, $input, $choice["text"]);

            $count++;
        }

    }

    return $choices;
}

但是，如果您安装了Gravity Forms Quiz Addon，并且想在标签内移动THOSE单选输入，则需要此代码。唯一的区别是if($field["type"] != "radio")被if($field["type"] != "quiz")替换。

// Gravity Forms Quiz - move radio input inside label
add_filter("gform_field_choices", "radio_input_inside_label", 10, 2);
function radio_input_inside_label($choices, $field){
    if($field["type"] != "quiz") // <--- CHANGE HERE
        return $choices;

    $choices = "";

    if(is_array($field["choices"])){
        $choice_id = 0;
        $count = 1;

        $logic_event = !empty($field["conditionalLogicFields"]) ? "onclick='gf_apply_rules(" . $field["formId"] . "," . GFCommon::json_encode($field["conditionalLogicFields"]) . ");'" : "";

        foreach($field["choices"] as $choice){
            $id = $field["id"] . '_' . $choice_id++;
            $field_value = !empty($choice["value"]) || rgar($field, "enableChoiceValue") ? $choice["value"] : $choice["text"];
            $checked = rgar($choice,"isSelected") ? "checked='checked'" : "";
            $tabindex = GFCommon::get_tabindex();

            $input = sprintf("<input name='input_%d' type='radio' value='%s' %s id='choice_%s' $tabindex $logic_event />", $field["id"], esc_attr($field_value), $checked, $id);
            $choices .= sprintf("<li class='gchoice_$id'><label for='choice_%s'>%s %s</label></li>", $id, $input, $choice["text"]);

            $count++;
        }

    }

    return $choices;
}
