    Replace image with an uploaded one?

    in PHP Coding Help

    Posted

    Hi. I have a script here that will let users upload an image to my website but I just can't figure out how to save the uploaded image as "upload/logo.png" so that it will replace the already existing "upload/logo.png".

    Help would be greatly appreciated.

     

    <html>
<body>

<form action="" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>

</body>
</html> 


<?php
if(isset($_POST['submit']) && !empty($_FILES["file"]["name"])) {
$timestamp = time();
$target = "upload/"; 
$target = $target . basename($_FILES['uploaded']['name']) ; 
$ok=1;

$allowed_types = array("image/gif","image/jpeg","image/pjpeg","image/png","image/bmp");
$allowed_extensions = array("gif","png","jpg","bmp");

if ($_FILES['file']['size'] > 350000) {
$max_size =  round(350000 / 1024);
echo "Your file is too large. Maximum $max_size Kb is allowed. <br>"; 
$ok=0;
} 

if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_FILES["file"]["error"] . "<br />";
$ok=0;
} else {
  
$path_parts = pathinfo(strtolower($_FILES["file"]["name"]));
  
if(in_array($_FILES["file"]["type"],$allowed_types) && in_array($path_parts["extension"],$allowed_extensions)){
$filename = $timestamp."-".$_FILES["file"]["name"]; 
  echo "Name: " . $filename . "<br />";
  echo "Type: " . $_FILES["file"]["type"] . "<br />";
  $path_parts = pathinfo($_FILES["file"]["name"]);
  echo "Extension: " . $path_parts["extension"] . "<br />";
  echo "Size: " . round($_FILES["file"]["size"] / 1024) . " Kb<br />";
  //echo "Stored in: " . $_FILES["file"]["tmp_name"]. " <br />";
  } else {
  echo "Type " . $_FILES["file"]["type"] . "  with extension " . $path_parts["extension"] . " not allowed <br />";
  $ok=0;
  }
}
if($ok == 1){
@move_uploaded_file($_FILES["file"]["tmp_name"], $target . $filename);
$file_location = $target . $filename;
if(file_exists($file_location)){
echo "Uploaded to <a href='$file_location'>$filename</a> <br />";
} else {
echo "There was a problem saving the file. <br />";
}

}
} else {
echo "Select your file to upload.";
}

?>

     

    Thanks!

    Include file two directories up?

    in PHP Coding Help

    Posted

    How do I include a file that is located two directories above the file that I want to include the file into?

     

    My absolute hosting path is /home/content/52/8840652/html if this would be of any use. I'm not quite sure about the PHP include functions.

     

    Any help would be greatly appreciated,

     

    Thanks!

    Listing files along with description and image?

    in PHP Coding Help

    Hi.

     

    I'm making a website where users can upload files along with title, description and image.

     

    I can get them making the page (str replace) but I only know how to list the files with just the file title in a basic links directory.

    Any ideas how I could include title, description and a picture (as well as the link to the page). Sort of like with Youtube search results or engine001.com/games.htm?

     

    Any help would be greatly appreciated.

     

    Thanks :D

     

    are you using a database to store this information?

    a little more information on the subject would be helpful.

     

    I'm not. Basically I have a file upload page and on that page there's the title, description, image and file fields.

    When a user clicks submit a second page, process.php, uploads the file and image and puts the file into the files directory, the image into the pictures directory. Then, using a default template and str replace, the description, title and username are filled out. The picture is sourced from the picture directory and the download link from the files directory (again using str_replace).

    Although I do have a MySQL for the users I'm not using a database for the files. Only the three php pages, upload, process and template.

    Any ideas?

     

    Thanks!

    There seems to be items missing from that tutorial.

     

    Don't foget to have a folder named upload in the same directory as this script is, or change your target path.

    pretty sure I added the essentials to this, also included a timestamp to the front of the file name so you don't have duplicate named files.

     

    <html>
<body>

<form action="" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>

</body>
</html> 


<?php
if(isset($_POST['submit']) && !empty($_FILES["file"]["name"])) {
$timestamp = time();
$target = "upload/"; 
$target = $target . basename($_FILES['uploaded']['name']) ; 
$ok=1;

$allowed_types = array("image/gif","image/jpeg","image/pjpeg","image/png","image/bmp");
$allowed_extensions = array("gif","png","jpg","bmp");

if ($_FILES['file']['size'] > 350000) {
$max_size =  round(350000 / 1024);
echo "Your file is too large. Maximum $max_size Kb is allowed. <br>"; 
$ok=0;
} 

if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_FILES["file"]["error"] . "<br />";
$ok=0;
} else {
  
$path_parts = pathinfo(strtolower($_FILES["file"]["name"]));
  
if(in_array($_FILES["file"]["type"],$allowed_types) && in_array($path_parts["extension"],$allowed_extensions)){
$filename = $timestamp."-".$_FILES["file"]["name"]; 
  echo "Name: " . $filename . "<br />";
  echo "Type: " . $_FILES["file"]["type"] . "<br />";
  $path_parts = pathinfo($_FILES["file"]["name"]);
  echo "Extension: " . $path_parts["extension"] . "<br />";
  echo "Size: " . round($_FILES["file"]["size"] / 1024) . " Kb<br />";
  //echo "Stored in: " . $_FILES["file"]["tmp_name"]. " <br />";
  } else {
  echo "Type " . $_FILES["file"]["type"] . "  with extension " . $path_parts["extension"] . " not allowed <br />";
  $ok=0;
  }
}
if($ok == 1){
@move_uploaded_file($_FILES["file"]["tmp_name"], $target . $filename);
$file_location = $target . $filename;
if(file_exists($file_location)){
echo "Uploaded to <a href='$file_location'>$filename</a> <br />";
} else {
echo "There was a problem saving the file. <br />";
}

}
} else {
echo "Select your file to upload.";
}

?>

     

    You can use the file types with if/else or a switch statement and display a resized image if was an image, a link if was a file, an embed if audio or video, etc....

    I just made it a hyperlink for simplicity.

     

    You are a life saver. Thank you very very very much.  :D

    Some changes to the previous code, also added checking for extensions within the allowed mime types.

     

    <html>
<body>

<form action="" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>

</body>
</html> 


<?php
if(isset($_POST['submit']) && !empty($_FILES["file"]["name"])) {

$allowed_types = array("image/gif","image/jpeg","image/pjpeg","image/png","image/bmp");
$allowed_extensions = array("gif","png","jpg","bmp");

if ($_FILES["file"]["error"] > 0) {
  echo "Error: " . $_FILES["file"]["error"] . "<br />";
  } else {
  
$path_parts = pathinfo(strtolower($_FILES["file"]["name"]));
  
if(in_array($_FILES["file"]["type"],$allowed_types) && in_array($path_parts["extension"],$allowed_extensions)){  
  echo "Upload: " . $_FILES["file"]["name"] . "<br />";
  echo "Type: " . $_FILES["file"]["type"] . "<br />";
  $path_parts = pathinfo($_FILES["file"]["name"]);
  echo "Extension: " . $path_parts["extension"] . "<br />";
  echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
  echo "Stored in: " . $_FILES["file"]["tmp_name"];
  } else {
  echo "Type " . $_FILES["file"]["type"] . "  with extension " . $path_parts["extension"] . " not allowed";
  }
}

} else {
echo "Select your file to upload.";
}

?>

    Thanks! Quick question though, where do I put your script in proportion to the original? I tried mingling it in but must have put it in the wrong place because some times I got it being treated as two different scripts and sometimes being presented with an error?

    Where do I put the original?

     

    Thanks!

    you will want to the compare the mime of the file to the $_FILES[filename][type] value.

    I like to store the valid extensions in an array and compare the array of values to the mime type of the given file using a conditional statement.

    May you explain how to do that?

    Hi. I'm making a file-sharing website but how do I stop users from uploading certain extensions?

    Here is my script so far:

     

    <?php

    session_start();

    $file_name = $HTTP_POST_FILES['ufile']['name'];

    $random_digit=rand(0000,9999);

    $new_file_name=$random_digit.$file_name;

    $path= "upload/".$new_file_name;

    if($ufile !=none)

    {

    if(copy($HTTP_POST_FILES['ufile']['tmp_name'], $path))

    {

    echo "Successful<BR/>";

    }

    else

    {

    echo "Error";

    }

    }

    ?>
