在codeigniter中更新多张图片

Question

我不明白为什么它只更新1张图片并循环播放

以下是html表单代码

<form enctype="multipart/form-data" action="<?php echo base_url('admin/edit_property/' . $property['property_id']); ?>" class="form-horizontal" method="post" >
    <div class="form-group">
        <label class="col-md-3 control-label">Select Images</label>
        <div class="col-md-8" style="margin-top:1%;">
            <input type="file" name="files[]" id="file" multiple="multiple" > 

            <?php 
            foreach ($property_image as $property_images) { 
                ?> 
                <img src="<?php echo base_url() . 'uploads/' . $property_images['image_name']; ?>" width="42" height="42">
                <?php 
            } 
            ?>
        </div>

在控制器中，我正在浏览文件

foreach($_FILES["files"]["tmp_name"] as $key => $tmp_name) {

    $temps = $_FILES["files"]["tmp_name"][$key];
    $new_file_name = $_FILES["files"]["name"][$key];

    move_uploaded_file($temps, "uploads/" . $new_file_name);                                           
    $this->crud_model->updated_property_image_records($new_file_name, $id); 

 }

这是模型中的查询

function updated_property_image_records($new_file_name, $id) {
    $update = $this->db->query("UPDATE property_image SET image_name='$new_file_name' where property_id= '$id' ");
}
