Question

<?php
$repeat_days = "0,1,2";
$repeat_array = explode(",", $repeat_days);
foreach ($repeat_array as $repeat_array1): ?>
    <label class="checkbox-inline">
        <input type="checkbox" name="day[]" value="0">SUN
    </label>
    <label class="checkbox-inline">
        <input type="checkbox" name="day[]" value="1">MON
    </label>
    <label class="checkbox-inline">
        <input type="checkbox" name="day[]" value="2">TUE
    </label>
    <label class="checkbox-inline">
        <input type="checkbox" name="day[]" value="3">WED
    </label>
    <label class="checkbox-inline">
        <input type="checkbox" name="day[]" value="4">THU
    </label>
    <label class="checkbox-inline">
        <input type="checkbox" name="day[]" value="5">FRI
    </label>
    <label class="checkbox-inline">
        <input type="checkbox" name="day[]" value="6">SAT
    </label>
<?php endforeach; ?>

我需要在php中编辑时自动选中一个复选框。在这里我输入了一个静态值，如0,1,2。 0-> SUN，1-> MON，2-> TUE。在这种情况下，如果foreach值等于复选框值，则会自动选中该复选框。我怎么能解决这个朋友呢？

请指导我

    </label>

Answer 2

$days = array("SUN","MON","TUE","WED","THU","FRI","SAT");
$checked = array(0,1,2);


foreach ($days as $key => $day) {
    if (in_array($key, $checked)){
        $status = "checked";
    } else {
        $status = "";
    }

    $checkbox = '
    <label class="checkbox-inline">
        <input type="checkbox" name="day[]" value="'.$key.'" '.$status.'>'.$day.'
    </label>
    ';
    echo $checkbox;
}

Answer 3

<?php

$days = array('Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat');

$repeat_days = "0,1,2";
$repeat_array = explode(",", $repeat_days);

foreach($days as $index => $day) {
    echo '<label class="checkbox-inline"><input type="checkbox" name="day[]" value="'.$index.'"'.(in_array($index,$repeat_array)? ' checked' :'').'>'.$day.'</label>';
}
