Php 为什么无法从多个字段上载多个文件？

我有一张表格。我正试图从Codeigniter中的3个不同输入字段上传3个文件。 三个领域是：保险、许可和注册。 字段中的路径准确地保存在数据库中，但只有一个文件指向文件夹。这三个文件有三个不同的文件夹。注册文件已上载到保险文件夹中。未上载许可证和注册

<?php
if (!empty($_FILES['insurance']['name'])) {
    $path = $_FILES['insurance']['name'];
    $ext = pathinfo($path, PATHINFO_EXTENSION);
    $rand = 'ins_' . rand(1, 500) . rand(500, 1000) . rand(1, 500);
    $config['upload_path'] = BASEPATH . "../images/insurance/";
    $config['allowed_types'] = '*';
    $config['file_name'] = $rand;
    $this->load->library('upload', $config);
    $this->upload->overwrite = true;
    $this->upload->do_upload('insurance');
    $data = $this->upload->data();
    $_POST['insurance'] = $this->config->base_url() . "images/insurance/" . $rand . '.' . $ext;
} else{
    echo "Error in uploading Insurance Photo";
}

if (!empty($_FILES['permit']['name'])) {
    $path = $_FILES['permit']['name'];
    $ext = pathinfo($path, PATHINFO_EXTENSION);
    $rand = 'pmt_' . rand(1, 500) . rand(500, 1000) . rand(1, 500);
    $config['upload_path'] = BASEPATH . "../images/permit/";
    $config['allowed_types'] = '*';
    $config['file_name'] = $rand;
    $this->load->library('upload', $config);
    $this->upload->overwrite = true;
    $this->upload->do_upload('permit');
    $data = $this->upload->data();
    $_POST['permit'] = $this->config->base_url() . "images/permit/" . $rand . '.' . $ext;
} else{
    echo "Error in uploading Permit Photo";
}

if (!empty($_FILES['registration']['name'])) {
    $path = $_FILES['registration']['name'];
    $ext = pathinfo($path, PATHINFO_EXTENSION);
    $rand = 'reg_' . rand(1, 500) . rand(500, 1000) . rand(1, 500);
    $config['upload_path'] = BASEPATH . "../images/registration/";
    $config['allowed_types'] = '*';
    $config['file_name'] = $rand;
    $this->load->library('upload', $config);
    $this->upload->overwrite = true;
    $this->upload->do_upload('registration');
    $data = $this->upload->data();
    $_POST['registration'] = $this->config->base_url() . "images/registration/" . $rand . '.' . $ext;
} else{
    echo "Error in uploading Registration Photo";
}
?>

这是上传的控制器代码

<?php
if (!empty($_FILES['insurance']['name'])) {
    $path = $_FILES['insurance']['name'];
    $ext = pathinfo($path, PATHINFO_EXTENSION);
    $rand = 'ins_' . rand(1, 500) . rand(500, 1000) . rand(1, 500);
    $config['upload_path'] = BASEPATH . "../images/insurance/";
    $config['allowed_types'] = '*';
    $config['file_name'] = $rand;
    $this->load->library('upload', $config);
    $this->upload->overwrite = true;
    $this->upload->do_upload('insurance');
    $data = $this->upload->data();
    $_POST['insurance'] = $this->config->base_url() . "images/insurance/" . $rand . '.' . $ext;
} else{
    echo "Error in uploading Insurance Photo";
}

if (!empty($_FILES['permit']['name'])) {
    $path = $_FILES['permit']['name'];
    $ext = pathinfo($path, PATHINFO_EXTENSION);
    $rand = 'pmt_' . rand(1, 500) . rand(500, 1000) . rand(1, 500);
    $config['upload_path'] = BASEPATH . "../images/permit/";
    $config['allowed_types'] = '*';
    $config['file_name'] = $rand;
    $this->load->library('upload', $config);
    $this->upload->overwrite = true;
    $this->upload->do_upload('permit');
    $data = $this->upload->data();
    $_POST['permit'] = $this->config->base_url() . "images/permit/" . $rand . '.' . $ext;

    echo "Error in uploading Permit Photo";
}

if (!empty($_FILES['registration']['name'])) {
    $path = $_FILES['registration']['name'];
    $ext = pathinfo($path, PATHINFO_EXTENSION);

您需要使用

$config

初始化上载库，而不是再次加载。您只加载一次上载库，不进行任何配置，然后每次使用配置初始化它

$this->load->library('upload');
// (stuff for first file)
$this->upload->initialize($config);
// (stuff for second file)
$this->upload->initialize($config);
// (...)
