Question

我正在编辑CMS的页面。我正在检查是否有任何输入是空的（因为这是一个编辑页面，我回显了值，所以不会有任何空字段，它甚至不应该输入if循环）即使它进入它应该显示一些错误但它没有。

if(isset($_POST['update'])){
  $update_id = $_GET['edit_form'];
  $post_title1=$_POST['title'];
  $post_keywords1=$_POST['keywords'];
  $post_content1=$_POST['content'];
  $post_category1=$_POST['category'];
  $post_image1=$_FILES['image']['name'];
  $image_tmp = $_FILES['image']['tmp_name'];
  echo $post_content1 ;
  if($post_title1 == '' or $post_keywords1 == '' or $post_content1 == '' or $post_category1 == '' or $post_image1 == '') {
    echo " <script>some value is empty plz check </script>" ; 
    exit();
  }
  else {
    echo $post_content1 ;
    move_uploaded_file($image_tmp,"../final/images/$post_image1");
    $update_query = "update articles set article_title='$post_title1' , article_content='$post_content1', article_image='$post_image1', category='$post_category1', article_keywords='$post_keywords1' WHERE article_id='$post_id'";
    if(mysqli_query($conn,$update_query)== 1 ) {
      echo "<script> alert('article updated')</script> " ;
    }
    else {
      echo "failed".mysqli_error($conn); 
    }
  }
}

Answer 1

echo " <script>some value is empty plz check </script>" ;

这只包含脚本标记中的文本，该标记将不执行任何操作。您在其他陈述中需要alert此错误。

echo " <script>alert('a required value is empty please check your input'); </script>" ;

php没有退出条件
