php copy()不起作用

Question

我想使用ajax调用做一个简单的复制.这是我的代码,但它不起作用.我得到:副本(../../ images/merchant/particulars/208 /)无法打开流:在scriptname.php第x行的某个/ filepath中有一个目录,有点错误.

corrected code: 

$dir_to_make = '../../images/merchant/particulars/'.$copytothisstore;
$dir = '../../images/merchant/particulars/'.$copytothisstore.'  /'.$copyvalue;
$image_to_copy = '../../images/merchant/particulars/'.$copyfromthisstore.'/'.$copyvalue;






    if(is_file($image_to_copy)){

        //chk if there is a folder created for this store
        if(!is_dir($dir_to_make)){
              mkdir($dir_to_make, 0755);  
              chmod($dir_to_make, 0755);

              //copy the image 
              if (!copy($image_to_copy,$dir)) {
                  echo "failed to copy $image_to_copy\n";
              } else {
                  echo"all is well!!";
              }

           } else {
               chmod($dir_to_make, 0755);
               if (!copy($image_to_copy,$dir)) {
                  echo "failed to copy $image_to_copy\n";
              } else {
                  echo"all is well!!";
              }

           }


           echo"$image_to_copy does exist!";
        } else{
            echo"$image_to_copy does not exist!";
        }

请阅读你的错误.

copy(../../images/merchant/particulars/208/) failed to open stream: Is a directory in some/filepath

它说你的源文件不是文件,而是目录.

简单的调试总能解决您的问题:

$image_to_copy ='../../images/merchant/particulars/'.$copyfromthisstore.'/'.$copyvalue;
echo $image_to_copy; // yes, that could give you the answer

它会告诉你,那$copyvalue你的例子是空的.

如果你想知道为什么会这样TRUE......

if(file_exists($image_to_copy)){

..是因为目录../../images/merchant/particulars/208/确实存在.

正如手册所说:

• file_exists() - 如果filename指定的文件或目录存在,则返回TRUE; 否则为FALSE.

您应该将其更改为:

if(is_file($image_to_copy)){

• is_file() - 如果文件名存在且是常规文件,则返回TRUE,否则返回FALSE.

另一件事是目的地shuld也是文件:

copy($image_to_copy, $dir.'file.jpg');
