Question

我想过滤此表单中的空输入，因此我输入了一个表单来制作它，我使用了If / else条件。

如果条件不起作用..但是条件正在按我的意愿运作。有什么问题？

PHP：

if($_GET['rm'] == 'edit'){
    $rm_edit_query = $db->query("SELECT * FROM reminders WHERE r_id = '".$_GET['r_id']."'");
    $rm_edit_query_fetch = $rm_edit_query->fetch_array(MYSQLI_ASSOC);
    if(isset($_POST['save-reminder-changes'])){
        if(empty($_POST['rm-name-e']) or empty($_POST['rm-details-e']) or empty($_POST['rm-date-e']) or empty($_POST['rm-time-e'])){
            ?>
            <h3 style="margin-top: 30px;text-align: center;font-size: 25px;color: red;" dir="rtl">يجب كتابة جميع البيانات لحفظ التغييرات.</h3>
            <?php
        }else{
            ?>
            <style type="text/css">
                .rm-table, .main h3, .reminder-submit, .main hr {
                    display: none;
                }
                .succeed {
                    display: block !important;
                }
            </style>
            <?php
            $rm_name = $_POST['rm-name-e'];
            $rm_details = $_POST['rm-details-e'];
            $rm_date = $_POST['rm-date-e'];
            $rm_time = $_POST['rm-time-e'];
            $rm_insert_query = $db->query("UPDATE reminders SET r_name = '".$rm_name."', r_details = '".$rm_details."', r_date = '".$rm_date."', r_time = '".$rm_time."' WHERE r_id = '".$_GET['r_id']."'");
            ?>
            <h3 dir="rtl" class="succeed" style="margin-top: 30px;text-align: center;font-size: 25px;color: green;">تم حفظ التعديلات. <a href="reminder.php">Show reminders</a></h3>
            <?php
            exit;
        }
    }
    ?>
    <style type="text/css">
        .rm-table, .main h3, .reminder-submit, .main hr {
            display: none;
        }
    </style>
    <form action="reminder.php?rm=edit&r_id=<?php echo $_GET['r_id']; ?>" method="post">
        <table class="rm" width="auto" border="0px">
            <tr>
                <td class="rm-form-text">Reminder date/time :</td>
                <td><input autofocus="" name="rm-date-e" type="date" id="rm" value="<?php echo $rm_edit_query_fetch['r_date'] ?>" /> / <input name="rm-time-e" type="time" id="rm" value="<?php echo $rm_edit_query_fetch['r_time'];?>" />
            </tr>
            <tr>
                <td class="rm-form-text">Remimnder name :</td>
                <td><input name="rm-name-e" type="text" id="rm" value="<?php echo $rm_edit_query_fetch['r_name'] ?>" /></td>
            </tr>
            <tr>
                <td class="rm-form-text">Reminder details :</td>
                <td><textarea dir="rtl" name="rm-details-e" id="rm-ta"><?php echo $rm_edit_query_fetch['r_details'] ?></textarea></td>
            </tr>
            <tr>
                <td colspan="2"><input name="save-reminder-changes" type="submit" class="sp-submit" value="Save changes!" /></td>
            </tr>
        </table>
    </form>
    <?php
    exit;
}

Answer 1

我使用了This validation tool，似乎问题是在条件中使用or。您只需将or替换为||，如下所示：

<?php
if($_GET['rm'] == 'edit'){
    $rm_edit_query = $db->query("SELECT * FROM reminders WHERE r_id = '".$_GET['r_id']."'");
    $rm_edit_query_fetch = $rm_edit_query->fetch_array(MYSQLI_ASSOC);
    if(isset($_POST['save-reminder-changes'])){
        if(empty($_POST['rm-name-e']) || empty($_POST['rm-details-e']) || empty($_POST['rm-date-e']) || empty($_POST['rm-time-e'])){
?>
<h3 style="margin-top: 30px;text-align: center;font-size: 25px;color: red;" dir="rtl">يجب كتابة جميع البيانات لحفظ التغييرات.</h3>
<?php
        }
        else {
?>
<style type="text/css">
    .rm-table, .main h3, .reminder-submit, .main hr {
        display: none;
    }
    .succeed {
        display: block !important;
    }
</style>
<?php
    $rm_name = $_POST['rm-name-e'];
    $rm_details = $_POST['rm-details-e'];
    $rm_date = $_POST['rm-date-e'];
    $rm_time = $_POST['rm-time-e'];
    $rm_insert_query = $db->query("UPDATE reminders SET r_name = '".$rm_name."', r_details = '".$rm_details."', r_date = '".$rm_date."', r_time = '".$rm_time."' WHERE r_id = '".$_GET['r_id']."'");
?>
<h3 dir="rtl" class="succeed" style="margin-top: 30px;text-align: center;font-size: 25px;color: green;">تم حفظ التعديلات. <a href="reminder.php">Show reminders</a></h3>
<?php
        exit;
        }
    }
?>
<style type="text/css">
    .rm-table, .main h3, .reminder-submit, .main hr {
        display: none;
    }
</style>
<form action="reminder.php?rm=edit&r_id=<?php echo $_GET['r_id']; ?>" method="post">
    <table class="rm" width="auto" border="0px">
        <tr>
            <td class="rm-form-text">Reminder date/time :</td>
            <td><input autofocus="" name="rm-date-e" type="date" id="rm" value="<?php echo $rm_edit_query_fetch['r_date'] ?>" /> / <input name="rm-time-e" type="time" id="rm" value="<?php echo $rm_edit_query_fetch['r_time'];?>" />
        </tr>
        <tr>
            <td class="rm-form-text">Remimnder name :</td>
            <td><input name="rm-name-e" type="text" id="rm" value="<?php echo $rm_edit_query_fetch['r_name'] ?>" /></td>
        </tr>
        <tr>
            <td class="rm-form-text">Reminder details :</td>
            <td><textarea dir="rtl" name="rm-details-e" id="rm-ta"><?php echo $rm_edit_query_fetch['r_details'] ?></textarea></td>
        </tr>
        <tr>
            <td colspan="2"><input name="save-reminder-changes" type="submit" class="sp-submit" value="Save changes!" /></td>
        </tr>
    </table>
</form>
<?php
    exit;
}

PHP empty（）函数不起作用
