CodeIgniter - 图片提交按钮不工作 [英] CodeIgniter - Image submit button not working

问题描述

我使用CI为客户端创建项目，我有一个提交按钮作为图像，但似乎没有提交表单，我现在的代码是

 < input type =imagename =trialSubmitid =trialSubmitsrc =<？php echo base_url /subscribe_free.jpg';？> style =height：29px; width：207px; border-width：0px; /> 
  

我现在必须使用的代码如下

 < input type =submitname =trialSubmitvalue =Subscribe Freeid =class =button/& 
  

如果任何人可以说明为什么它不工作的图像， / p>

干杯，

解决方案

  **视图内（如我的案例中的商业）**，
 
 
 
< form action =<？php echo site_url（）？& / douploadmethod =postenctype =multipart / form-data> 
< b>选择要上传的图片（最大尺寸：500 kb，jpg，jpeg）：< / b> 
< input style =color：＃00A76Ftype =filename =fileToUploadid =fileToUpload> 
< div class =input-groupstyle =left：10％; width：85％;> 
 
< input class =btn btn-success pull-rightstyle =background：＃00A76Ftype =submitvalue =上传图片name =submit 
 
 
 
< / div> 
 
 
< / form> 
< div class =modal-body> 
< div id =user_data> 
<？php 
 if（！empty（$ massage））{
 echo $ massage; 
 
} 
？> 
< / div> 
 
 **在控制器中定义一个方法** 
 
 public function doupload（）{
 $ root1 = $ _SERVER ['DOCUMENT_ROOT'] ;; 
 
 $ target_dir = $ root1。/ nawaloka / uploads /; 
 
 // $ target_dir = $ root1。/ nawaloka / application /; 
 $ target_file = $ target_dir。 basename（$ _ FILES [fileToUpload] [name]）; 
 
 $ uploadOk = 1; 
 $ imageFileType = pathinfo（$ target_file，PATHINFO_EXTENSION）; 
 
 //检查文件是否已经存在
 //检查文件大小
 if（$ _FILES [fileToUpload] [size]> 500000）{
 $ data ['massage'] =对不起，您的文件太大了。 
 $ partials = array（'content'=>'Admin / comerciales'）; 
 $ this-> template-> load（'template / admin_template'，$ partials，$ data）; 
 
 $ uploadOk = 0; 
} 
 if（is_dir（$ target_dir）&& is_writable（$ target_dir））{
 
 //上传逻辑
} else {
 echo'上传目录不可写，或不存在。 
} 
 
 
 
 //允许某些文件格式
 if（$ imageFileType！=jpg& $ imageFileType！=jpeg ）{
 $ data ['massage'] =对不起，只允许JPG，JPEG文件。 
 $ partials = array（'content'=>'Admin / comerciales'）; 
 $ this-> template-> load（'template / admin_template'，$ partials，$ data）; 
 
 $ uploadOk = 0; 
} 
 //检查$ uploadOk是否由于错误而设置为0 
 if（$ uploadOk == 0）{
 $ data ['massage'] =对不起，您的文件未上传。 
 $ partials = array（'content'=>'Admin / comerciales'）; 
 $ this-> template-> load（'template / admin_template'，$ partials，$ data）; 
 
 //如果一切正常，尝试上传文件
} else {
 array_map（'unlink'，glob（/ var / www / html / nawaloka / uploads / *））; 
 
 if（move_uploaded_file（$ _ FILES [fileToUpload] [tmp_name]，/ var / www / html / nawaloka / uploads / shamith.jpg））{
 $ data ['massage'] =图像。 basename（$ _FILES [fileToUpload] [name]）。 已上传。 
 $ partials = array（'content'=>'Admin / comerciales'）; 
 $ this-> template-> load（'template / admin_template'，$ partials，$ data）; 
 
 
 // echo文件。 basename（$ _FILES [fileToUpload] [name]）。 已上传。 
} else {
 
 $ data ['massage'] =很抱歉，上传文件时出错。 
 $ partials = array（'content'=>'Admin / comerciales'）; 
 $ this-> template-> load（'template / admin_template'，$ partials，$ data）; 
} 
} 
 
 
 
 
} 
  

I am using CI to create a project for a client, I have a submit button as an image but it doesn't seem to be submitting the form, the code I have at the moment is.

<input type="image" name="trialSubmit" id="trialSubmit" src="<?php echo base_url().'images/subscribe_free.jpg'; ?>" style="height:29px;width:207px;border-width:0px;" />

The code I have to use at the moment is as follows

<input type="submit" name="trialSubmit" value=" Subscribe Free " id="" class="button" />

If anyone could shed some light on why it's not working with the image, that would be tight.

Cheers,

解决方案

**inside the view(as comerciales in my case)**, 



    <form action= "<?php echo site_url()?>/admin/doupload"  method="post" enctype="multipart/form-data" >
  <b>  Select the image to upload( Maximum size 500 kb, jpg, jpeg): </b>
    <input   style="color:#00A76F" type="file" name="fileToUpload" id="fileToUpload">
   <div  class="input-group" style="left:10%;width:85%;">

 <input class="btn btn-success pull-right" style="background:#00A76F" type="submit" value="Upload Image" name="submit">



</div>


</form>
   <div class="modal-body">
                    <div id="user_data">
                      <?php
                      if (!empty($massage)){
                          echo $massage ;

                      }
                        ?>
                    </div>

**inside the controller define a method**

    public function doupload(){
       $root1 = $_SERVER['DOCUMENT_ROOT'];;

        $target_dir =  $root1."/nawaloka/uploads/";

             // $target_dir =  $root1."/nawaloka/application/";
          $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

// Check if file already exists
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
   $data['massage']= "Sorry, your file is too large.";
            $partials = array('content' => 'Admin/comerciales');
            $this->template->load('template/admin_template', $partials,$data);

    $uploadOk = 0;
}
if (is_dir($target_dir) && is_writable($target_dir)) {

    // do upload logic here
} else {
    echo 'Upload directory is not writable, or does not exist.';
}



// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "jpeg" ) {
     $data['massage']= "Sorry, only JPG, JPEG files are allowed.";
            $partials = array('content' => 'Admin/comerciales');
            $this->template->load('template/admin_template', $partials,$data);

    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
   $data['massage']= "Sorry, your file was not uploaded.";
            $partials = array('content' => 'Admin/comerciales');
            $this->template->load('template/admin_template', $partials,$data);

// if everything is ok, try to upload file
} else {
            array_map('unlink', glob("/var/www/html/nawaloka/uploads/*"));

    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"],"/var/www/html/nawaloka/uploads/shamith.jpg")) {
           $data['massage']= "The image ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
            $partials = array('content' => 'Admin/comerciales');
            $this->template->load('template/admin_template', $partials,$data);


        //echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {

             $data['massage']= "Sorry, there was an error while uploading your file.";
            $partials = array('content' => 'Admin/comerciales');
            $this->template->load('template/admin_template', $partials,$data);
    }
}
