Question

Codeigniter代码：

if(is_dir('uploads/'.$data['pet'][0]['pet_hidenum'])){
    if(isset($this->input->post('lostimage1'))){
        $filedata = explode(',', $this->input->post('lostimage1'));
        $pos  = strpos($this->input->post('lostimage1'), ';');
        $type = explode(':', substr($this->input->post('lostimage1'), 0, $pos))[1];
        $type = '.'.$type;
        $type = str_replace('image/', '', $type);
        $img['img'] = $img['img'].''.$type;
        write_file('./uploads/'.$data['pet'][0]['pet_hidenum'].'/'.$img['img'], base64_decode($filedata[1]));
    }
}

为什么这个错误出现在任何人身上[租约帮助我如何解决这个问题？

当您使用旧版本的php时，会发生这种情况，因此您无法执行explode(':', substr($this->input->post('lostimage1'), 0, $pos))[1];

试试这个：

if(is_dir('uploads/'.$data['pet'][0]['pet_hidenum'])){
if(isset($this->input->post('lostimage1'))){
    $filedata = explode(',', $this->input->post('lostimage1'));
    $pos  = strpos($this->input->post('lostimage1'), ';');
    $aux = substr($this->input->post('lostimage1'), 0, $pos);
    $type = explode(':', $aux)[1];
    $type = '.'.$type;
    $type = str_replace('image/', '', $type);
    $img['img'] = $img['img'].''.$type;
    write_file('./uploads/'.$data['pet'][0]['pet_hidenum'].'/'.$img['img'], base64_decode($filedata[1]));
}
}

Codeigniter在写上下文中不能使用方法返回值
