問題描述

好的，所以我經歷了一些與我的問題類似的問題，但我不知道該怎么處理我的問題。 我在我的 model 中有一個 function 從 db 獲取單個餐廳，並且我有一個字段將特定餐廳的所有營業日作為逗號分隔值保存，(1,2,3) 1 = 星期日 2 = 星期一 3 = 星期二以此類推，直到 7...

數據庫表

我想在餐廳有營業日時選中復選框，比如如果餐廳有 1、2、3，它應該從前端視圖檢查周日、周一和周二。這是我的 model ......抱歉這么久問題...請幫助如何做到這一點...

function get_single_restaurant($id){
    $this->db->from('restaurants');
    $this->db->where('id', $id);
    $query = $this->db->get();
    $output = '' ;
    foreach($query->result() as $row)

        $output .= '<div class="modal-header">

這是我在前端的視圖

前端視圖

這是我的 Controller

function getRestaurant(){
    $id = $this->input->post('restaurant_id');
    $data = $this->sm->get_single_restaurant($id);
    if($this->sm->get_single_restaurant($id)){
        echo $data;
    }else{
        $data = array(
            'StatusCode' => '0',
            'message' => 'Invalid request'
        );
        echo json_encode($data);
    }
}

您的問題似乎與javascript而不是php/codeigniter有關。
不過，您需要的是制作一個單獨的checkbox ，並為clicked時要選擇的所有字段賦予一個值（就像您正在做的那樣），給它一些id ，添加一個event(change) ，然后給attribute所有inputs及其日期編號和 select 相應。

我創建了一個工作片段（當然沒有php ），必要時會提到注釋。 看看對你有沒有幫助。 

 document.querySelector('#special').addEventListener('change', (event) => { // add event 'change' to id='special' let elements = event.target.value.split(','); // get the value and create an array by splitting it let checked = false; // default false if (event.target.checked) { // check if the checkbox is checked or unchecked checked = true; // change if checked } elements.forEach((item) => { // change the property of all the checkboxes where data-day = item document.querySelector('[data-day="'+item+'"]').checked = checked; }); })
 <input type="checkbox" value="1,2,3" id="special">1,2,3&nbsp; <,-- Give an id='special' and value='1,2,3' for Sunday, Monday. Tuesday <input type="checkbox" class="custom-control-input add_days" id='special' name="opening_days[]" id="view_sunday" value="'.$row->opening_days.'"> <label class="custom-control-label" for="view_sunday">'.$row->opening_days;'</label> --> <input type="checkbox" value="1" data-day="1" name="opening_days[]" id="view_monday">Sunday&nbsp; <;-- add attribut data-day with its value = day number --> <input type="checkbox" value="2" data-day="2" name="opening_days[]" id="view_monday">Monday&nbsp; <input type="checkbox" value="3" data-day="3" name="opening_days[]" id="view_tuesday">Tuesday&nbsp; <input type="checkbox" value="4" data-day="4" name="opening_days[]" id="view_wednesday">Wednesday&nbsp; <input type="checkbox" value="5" data-day="5" name="opening_days[]" id="view_thursday">Thursday&nbsp; <input type="checkbox" value="6" data-day="6" name="opening_days[]" id="view_friday">Friday&nbsp; <input type="checkbox" value="7" data-day="7" name="opening_days[]" id="view_saturday">Saturday&nbsp;

好的，所以我想，我誤解了你的問題，你想要的是檢查checkboxes與已經存儲在database中的值。 你可以這樣做 -

<input type="checkbox" value="<?php echo $row->opening_days; ?>" id="special"><?php echo $row->opening_days; ?>

<?php 
    // make an array of the values - 
    $element = explode(",", $row->opening_days));
?>

<input type="checkbox" value="1" data-day="1" name="opening_days[]" id="view_sunday" <?php echo in_array("1", $element) ? 'checked' : ''; ?>>Sunday 
<!-- if 1(day number) is present in array element then check else unchecked -->
<input type="checkbox" value="2" data-day="2" name="opening_days[]" id="view_monday" <?php echo in_array("2", $element) ? 'checked' : ''; ?>>Monday
<input type="checkbox" value="3" data-day="3" name="opening_days[]" id="view_tuesday" <?php echo in_array("3", $element) ? 'checked' : ''; ?>>Tuesday
<input type="checkbox" value="4" data-day="4" name="opening_days[]" id="view_wednesday" <?php echo in_array("4", $element) ? 'checked' : ''; ?>>Wednesday
<input type="checkbox" value="5" data-day="5" name="opening_days[]" id="view_thursday" <?php echo in_array("5", $element) ? 'checked' : ''; ?>>Thursday
<input type="checkbox" value="6" data-day="6" name="opening_days[]" id="view_friday" <?php echo in_array("6", $element) ? 'checked' : ''; ?>>Friday
<input type="checkbox" value="7" data-day="7" name="opening_days[]" id="view_saturday" <?php echo in_array("7", $element) ? 'checked' : ''; ?>>Saturday

首先，你不應該在model或controller上寫HTML 。 現在要回答您的問題，請查看我的答案的Edit 1部分，該代碼將起作用。 您只需要確保不要使用PHP標簽，因為您已經在PHP HTML

$output = '' ;
foreach($query->result() as $row){

    $output .= 'bla bla bla';
    $output .= '<input type="checkbox" value="'.$row->opening_days.'" id="special">'.$row->opening_days;

    $element = explode(",", $row->opening_days));

    $output .= '<input type="checkbox" value="1" data-day="1" name="opening_days[]" id="view_sunday" '. in_array("1", $element) ? "checked" : "".' >Sunday';
    $output .= '<input type="checkbox" value="2" data-day="2" name="opening_days[]" id="view_monday" '. in_array("2", $element) ? "checked" : "".' >Monday';
    $output .= '...'; // same for rest of the days
    $output .= 'bla bla bla';

    return $output;
}

由於{'}或{"}或{.}放錯位置，您可能會在上面的代碼中遇到一些語法錯誤，但我相信您有足夠的能力自己修復它們。
