好吧，我经历了一些与我的问题类似的问题，但我没有得到什么做我的.我有一个函数在我的模型中得到单一的餐厅从db，我有一个字段，持有所有的开放天的特定的餐厅作为逗号分隔的值，（1,2,3）1 =周日2 =周一3 =周二等7 ...
我想在餐厅有营业日的时候勾选复选框，比如如果餐厅一有1,2,3，它应该从前端视图中勾选周日，周一和周二...这是我的模型...。对不起，这么长的问题... Pls help to how to do it...。

这是我的前端视图
这是我的控制器

$data = $this->sm->get_single_restaurant($id);
if($this->sm->get_single_restaurant($id)){
echo $data;

'message' => 'Invalid request'
);
echo json_encode($data);
}
}
你的问题似乎与 javascript 而非 php/codeigniter. 然而，你需要的是做一个单独的 checkbox 并给它一个您希望被选择的所有字段的值，当 clicked(像你这样)，给它一些 id，增加一个 event(change)那就给 attribute 对所有 inputs 并据此进行选择。我已经创建了一个工作片段（不含 php 当然），必要的时候会提到评论。看看对你有没有帮助。
document.querySelector('#special').addEventListener('change', (event) => { // add event 'change' to id='special'
let elements = event.target.value.split(','); // get the value and create an array by splitting it
let checked = false; // default false
if (event.target.checked) { // check if the checkbox is checked or unchecked
checked = true; // change if checked
}
elements.forEach((item) => { // change the property of all the checkboxes where data-day = item
document.querySelector('[data-day="'+item+'"]').checked = checked;
});
})<input type="checkbox" value="1,2,3" id="special">1,2,3
<!--
Give an id='special' and value='1,2,3' for Sunday, Monday, Tuesday
<input type="checkbox" class="custom-control-input add_days" id='special' name="opening_days[]" id="view_sunday" value="'.$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 <!-- add attribut data-day with its value = day number -->
<input type="checkbox" value="2" data-day="2" name="opening_days[]" id="view_monday">Monday
<input type="checkbox" value="3" data-day="3" name="opening_days[]" id="view_tuesday">Tuesday
<input type="checkbox" value="4" data-day="4" name="opening_days[]" id="view_wednesday">Wednesday
<input type="checkbox" value="5" data-day="5" name="opening_days[]" id="view_thursday">Thursday
<input type="checkbox" value="6" data-day="6" name="opening_days[]" id="view_friday">Friday
<input type="checkbox" value="7" data-day="7" name="opening_days[]" id="view_saturday">Saturday 好吧，我想，我误解了你的问题，你想要的是检查你的 checkboxes 中已经存储的值。database.你可以这样做 -
<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，你千万不要写 HTML 关于 model 或 controller 对于这个问题。现在回答你的问题，看看 编辑1 我的答案的一部分，该代码将工作。你只需要确保不使用 PHP 标签，因为你已经在写 HTML 内 PHP -
$output = '' ;
foreach($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;
}
你可能会在上面的代码中遇到一些语法错误，因为放错了位置。{'} 或 {"} 或 {.} 但我相信你有足够的能力自己解决它们。
