Uploading File into Server

Before Uploading File into Server, we should know about $_FILES super global. By using this $_FILES super global we need to access some information from the uploaded file.

We should know the name of the uploaded file. And the size of the file, extension of the file that is being uploaded. And the temporary location of the file uploaded. Below is the information

We can read name of the file $_FILES[‘name-of-file-field’][‘name’]

We can get the size of the file $_FILES[‘name-of-the-field’][‘size’]. This file size is in bytes.

We can get the type of the file $_FIELS[‘name-of-the-field’][‘type’] . This is file type that is image, video or any other file type.

We can get the file’s temporary uploaded location by $_FILES[‘name-of-file-field’][‘tmp_name’]. We are going to use this information to move the uploaded file into our desired directory.PHP

1234$name = $_FILES[‘file’][‘name’];$size = $_FILES[‘file’][‘size’];$type = $_FILES[‘file’][‘type’];$tmp_name = $_FILES[‘file’][‘tmp_name’];

Till Now we have seen the basics, let’s get into the script.

Checking to see that if the file name is set and not empty. Then setting a directory variable, and moving file from temporary location to our desired location.PHP

12345678910if(isset($name) && !empty($name)){ $location = “uploads/”; if(move_uploaded_file($tmp_name, $location.$name)){ $smsg = “Uploaded Successfully”; }else{ $fmsg = “Failed to Upload File”; }}else{ $fmsg = “Please Select a File”;}

By using move_uploaded_file function, we are successfully uploading the file.

Next we need to add the validations or restrictions based on the file type and also based on the size.

Restrict File Upload size while Uploading in PHP

We can achieve this by simply writing an if else condition, we will use the file size from Files superglobal. Before doing this we should define a variable with maximum file size, here I’m using 100kb as my maximum file size. You can increase this to your need.PHP

1$max_size = 100000;

Add this condition inside the first if statement, below is the code.PHP

1234567891011121314if(isset($name) && !empty($name)){ if(($extension == $size<=$max_size){ $location = “uploads/”; if(move_uploaded_file($tmp_name, $location.$name)){ $smsg = “Uploaded Successfully”; }else{ $fmsg = “Failed to Upload File”; } }else{ $fmsg = “File size should be 100 KiloBytes”; }}else{ $fmsg = “Please Select a File”;}

Restrict File Upload based on Extension While Uploading

For restricting file uploads based on the extensions, it’s tricky but not that’s complicated. First of all, we need to read the file extension. For that We will write PHP code do this function, we will remove everything in front of the period and also the period in the file name. So, the remaining part is the is the file extension.

We can get the output by using two functions, one is strpos and the another one is substr.PHP

1$extension = substr($name, strpos($name, ‘.’) + 1);

Add the condition to check the file extension inside the filename checking condtion. We can use these conditions in combination with file size restriction condition.PHP

1234567891011121314if(isset($name) && !empty($name)){ if(($extension == “jpg” || $extension == “jpeg”) && $type == “image/jpeg” && $extension == $size<=$max_size){ $location = “uploads/”; if(move_uploaded_file($tmp_name, $location.$name)){ $smsg = “Uploaded Successfully”; }else{ $fmsg = “Failed to Upload File”; } }else{ $fmsg = “File size should be 100 KiloBytes & Only JPEG File”; }}else{ $fmsg = “Please Select a File”;}

Displaying Success and Failure Messages in PHP File Upload Script

I’ve already defined failed message variable as fmsg and sucess message variable as smsg, you can use this below code to print the messages. Add this code inside the form opening tag.PHP

12<?php if(isset($smsg)){ ?><div class=”alert alert-success” role=”alert”> <?php echo $smsg; ?> </div><?php } ?><?php if(isset($fmsg)){ ?><div class=”alert alert-danger” role=”alert”> <?php echo $fmsg; ?> </div><?php } ?>
