【问题描述】：

我想知道...

我永远无法将任何照片上传到我的文件夹和数据库中。我试了几千次。我做错了什么，请帮助我。

我可以添加用户好。这不是问题。但我尝试上传照片，但从未上传任何照片。我的代码：

控制器：

     public function insert () {

            $config['upload_path'] = './upload/user/';
            $config['allowed_types'] = 'jpg|jpeg|png|gif';
            $config['max_size'] = 1024;
            $config['max_width'] = 100;
            $config['max_height'] = 100;
            $config['file_name'] = rand(100,999);
            $config['overwrite'] = false;

            $this->load->library('upload', $config);
            if(!$this->upload->do_upload('userImg')) {

                $this->load->view('user');
            }


        $data = array (
        "userUsername" => $this->input->post("userUsername"),
        "userPass" => $this->input->post("userPass"),
        "userEmail" => $this->input->post("userEmail"),
        "userName" => $this->input->post("userName"),
        "userSurname" => $this->input->post("userSurname"),
        "userImg" => $this->input->post("userImg"),
        "userLang" => $this->input->post("userLang"),
        "userType" => $this->input->post("userType"),
        "userDate" => date('Y-m-d H:i:s'),
   );
    $insert = $this->db->insert("user", $data);
    if($insert) {
    redirect(base_url("user"));
   }else {

    redirect(base_url("user"));

   }

}

和我的查看页面添加用户

<form class="cmxform form-horizontal tasi-form" id="signupForm" method="post" enctype="multipart/form-data" action="<?php echo base_url(); ?>user/insert">
        <div class="form-group last">

【问题讨论】：

请提供您的错误信息。
@habib - 添加任何用户时我都不会出错。我只是无法将照片添加到我的目录和数据库中。
@AbdulAhmad Matin - 您的解决方案不会影响项目。谢谢你的心意。但是你能说我的问题的其他解决方案吗？我需要你的帮助。

【解决方案1】：

如果您的 url 正确并且图片没有错误，则使用它可以正常工作并且图片上传。我测试过了。

public function insert () {
    $config['upload_path'] = './upload/user';
    $config['allowed_types']        = 'jpeg|jpg|png|gif';
    $config['max_size']             = 1024;
    $config['max_width']            = 1000;
    $config['max_height']           = 1000;
    $new_name = time();
    $config['file_name'] = $new_name;
    $this->load->library('upload', $config);
    $this->upload->initialize($config);
    if ( ! $this->upload->do_upload('userImg'))
    {
        $error = array('error' => $this->upload->display_errors());
            echo json_encode($error);
    }
    else{
    $upload_data = $this->upload->data();
    $data = array (
        "userUsername" => $this->input->post("userUsername"),
        "userPass" => $this->input->post("userPass"),
        "userEmail" => $this->input->post("userEmail"),
        "userName" => $this->input->post("userName"),
        "userSurname" => $this->input->post("userSurname"),
        "userImg" => $upload_data['file_name'],
        "userLang" => $this->input->post("userLang"),
        "userType" => $this->input->post("userType"),
        "userDate" => date('Y-m-d H:i:s'),
    );
    $insert = $this->db->insert("user", $data);
    if($insert) {
        redirect(base_url("user"));
    }else {

        redirect(base_url("user"));

    } 
  }
}

您可以使用此代码进行更新

public function update($userId) {
        if (isset($_FILES) && $_FILES['userImg']['error'] == '0') {
            $config['upload_path'] = './upload/user';

            $config['max_width']            = 1000;
            $config['max_height']           = 1000;
            $new_name = $this->input->post("userUsername");
            $config['file_name'] = $new_name;
            $this->load->library('upload', $config);
            $this->upload->initialize($config);
            if ( ! $this->upload->do_upload('userImg'))
            {
                $error = array('error' => $this->upload->display_errors());
                echo json_encode($error);

【讨论】：

我没有出错，好吧谢谢你，但是当我选择要上传的照片时，现在没有照片上传系统。
如果您选择照片，if 循环可以工作并上传图片，但如果您不选择文件或文件有错误else 工作。
我明白了。但我选择一张照片并使用编辑用户按钮上传它。它没有上传我的照片。我看不到它的用户目录或数据库。我能做些什么呢？我的编辑按钮工作正常，因为它无需上传照片即可编辑其他所有信息。现在我无法上传任何关于编辑用户的照片。
因为您的图像大小不适合当前将其更改为。 $config['max_size'] = 5000; $config['max_width'] = 4024; $config['max_height'] = 4068;
不，兄弟，它不起作用。我改成你说的了。

使用此代码进行更新。在视图和控制器中。

【讨论】：

不，我接受此错误：{"error":" 您尝试上传的文件类型不被允许。"} 我选择 png-jpg-jpeg 的类型。它给了我一个错误。
好的，所以您只需上传带有此扩展名的图片jpeg|jpg|png|gif
不要将您的文件扩展名重命名为其他无法使用的扩展名。
我只上传jpeg、jpg、png等右扩展名。但它给了我同样的错误。
: ( .. 删除 $config['allowed_types'] = 'jpeg|jpg|png|gif'; 但这不是一个好主意
