Question

我试图在php循环中嵌套HTML代码。它给出了该块的错误。 “解析错误：语法错误，第119行的C：\ xampp \ htdocs \ cms \ admin \ categories.php中的文件意外结束”

<form action="categories.php" method="post">
                        <div class="form-group">
                            <label for="cat-title">Update</label>
                            <?php //EDIT & UPDATE //
                            if (isset($_GET['edit'])){
                                $edit_row_title = $_GET['edit'];
                                $query = "SELECT * FROM category WHERE cat_id = {$edit_row_title}";
                                $edit_query = mysqli_query($connect,$query);

                                while($row = mysqli_fetch_assoc($edit_query)){
                                    $cat_id = $row['cat_id'];
                                    $cat_title = $row['cat_title'];
                                      ?>
                                <input class="form-control" name="cat_title" type="text" value="<?php if(isset($cat_title)){echo $cat_title;} ?>">
                               <?php } ?> }

                            <input type="text"  name="cat-title" class="form-control" >
                        </div>
                        <div class="form-group">
                            <input class="btn btn-primary" type="submit" name="submit" value="Edit Category" >
                        </div>
                    </form>

但是当我在html代码之前放置大括号时，它可以工作。期待while循环无法正常工作。

<form action="categories.php" method="post">
                        <div class="form-group">
                            <label for="cat-title">Update</label>
                            <?php //EDIT & UPDATE //
                            if (isset($_GET['edit'])){
                                $edit_row_title = $_GET['edit'];
                                $query = "SELECT * FROM category WHERE cat_id = {$edit_row_title}";
                                $edit_query = mysqli_query($connect,$query);

                                while($row = mysqli_fetch_assoc($edit_query)){
                                    $cat_id = $row['cat_id'];
                                    $cat_title = $row['cat_title'];
                                    }  ?>
                                <input class="form-control" name="cat_title" type="text" value="<?php if(isset($cat_title)){echo $cat_title;} ?>">
                               <?php } ?> 

                            <input type="text"  name="cat-title" class="form-control" >
                        </div>
                        <div class="form-group">
                            <input class="btn btn-primary" type="submit" name="submit" value="Edit Category" >
                        </div>
                    </form>

Answer 1

更改

<?php } ?> }

要

<?php } }?>

更新代码

<form action="categories.php" method="post">
  <div class="form-group">
    <label for="cat-title">Update</label>
    <?php //EDIT & UPDATE //
    if (isset($_GET['edit'])){
      $edit_row_title = $_GET['edit'];
      $query = "SELECT * FROM category WHERE cat_id = {$edit_row_title}";
      $edit_query = mysqli_query($connect,$query);

      while($row = mysqli_fetch_assoc($edit_query)){
        $cat_id = $row['cat_id'];
        $cat_title = $row['cat_title'];
        ?>
        <input class="form-control" name="cat_title" type="text" value="<?php if(isset($cat_title)){echo $cat_title;} ?>">
      <?php } }?> //Changes
      <input type="text"  name="cat-title" class="form-control" >
  </div>
  <div class="form-group">
    <input class="btn btn-primary" type="submit" name="submit" value="Edit Category" >
  </div>
</form>

Answer 2

while($row = mysqli_fetch_assoc($edit_query)){
                                    $cat_id = $row['cat_id'];
                                    $cat_title = $row['cat_title'];
                                      ?>
                                <input class="form-control" name="cat_title" type="text" value="<?php if(isset($cat_title)){echo $cat_title;} ?>">
                               <?php } ?> }

在最后一行中，在结束PHP标记之后添加一个结束花括号。我假设它关闭if，但PHP不会解释它。因此，在文件的末尾，PHP仍然期望该块被关闭，从而导致解析错误。

Answer 3

请更新以下代码

$mutes = GameMute::where('expires_at ', '>', new DateTime('today'))->orderBy('created_at', 'asc')->get();

Answer 4

您必须将<?php } ?> }更改为<?php } }?>，您的问题才能解决。

以下是根据您给定的代码段更新的代码：

<form action="categories.php" method="post">
  <div class="form-group">
    <label for="cat-title">Update</label>
    <?php //EDIT & UPDATE //
    if (isset($_GET['edit'])){
      $edit_row_title = $_GET['edit'];
      $query = "SELECT * FROM category WHERE cat_id = {$edit_row_title}";
      $edit_query = mysqli_query($connect,$query);

      while($row = mysqli_fetch_assoc($edit_query)){
        $cat_id = $row['cat_id'];
        $cat_title = $row['cat_title'];
        ?>
        <input class="form-control" name="cat_title" type="text" value="<?php if(isset($cat_title)){echo $cat_title;} ?>">
      <?php } }?> //Changes => This changes requred on your code.
      <input type="text"  name="cat-title" class="form-control" >
  </div>
  <div class="form-group">
    <input class="btn btn-primary" type="submit" name="submit" value="Edit Category" >
  </div>
</form>
