I am stuck with  this code.I want to upload image through database and want to retrieve it  on the same page from database using blob datatype. Below is the code for my page.

 

file_insert.php:

 

<html>

<head><title>File Insert</title></head>

<body>

<h3>Please Choose a File and click Submit</h3>

 

<form enctype="multipart/form-data" action=

"<?php echo $_SERVER['PHP_SELF']; ?>" method="post">

<input type="hidden" name="MAX_FILE_SIZE" value="10000000" />

<input name="userfile" type="file" />

<input type="submit" value="Submit" />

</form>

 

<?php

 

// check if a file was submitted

if(!isset($_FILES['userfile']))

{

    echo '<p>Please select a file</p>';

}

else

{

    try {

    $msg= upload();  //this will upload your image

    echo $msg;  //Message showing success or failure.

    }

    catch(Exception $e) {

    echo $e->getMessage();

    echo 'Sorry, could not upload file';

    }

}

 

// the upload function

 

function upload() {

    include "file_constants.php";

    $maxsize = 10000000; //set to approx 10 MB

 

    //check associated error code

    if($_FILES['userfile']['error']==UPLOAD_ERR_OK) {

 

        //check whether file is uploaded with HTTP POST

        if(is_uploaded_file($_FILES['userfile']['tmp_name'])) {    

 

            //checks size of uploaded image on server side

            if( $_FILES['userfile']['size'] < $maxsize) {  

  

               //checks whether uploaded file is of image type

              

 

//if(strpos(mime_content_type($_FILES['userfile']['tmp_name']),"image")===0) {

                $finfo = finfo_open(FILEINFO_MIME_TYPE);

                if(strpos(finfo_file($finfo, 

 

$_FILES['userfile']['tmp_name']),"image")===0) {    

 

                    // prepare the image for insertion

                    $imgData =addslashes 

 

(file_get_contents($_FILES['userfile']['tmp_name']));

 

                    // put the image in the db...

                    // database connection

                    mysql_connect($host, $user, $pass) OR DIE (mysql_error());

 

                    // select the db

                    mysql_select_db ($db) OR DIE ("Unable to select 

 

db".mysql_error());

 

                    // our sql query

                    $sql = "INSERT INTO image_again_test

                    (image, name)

                    VALUES

                    ('{$imgData}', '{$_FILES['userfile']['name']}');";

 

                    // insert the image

                    mysql_query($sql) or die("Error in Query: " . mysql_error());

                    $msg='<p>Image successfully saved in database with id ='. 

 

mysql_insert_id().' </p>';

                }

                else

                    $msg="<p>Uploaded file is not an image.</p>";

            }

             else {

                // if the file is not less than the maximum allowed, print an error

                $msg='<div>File exceeds the Maximum File limit</div>

                <div>Maximum File limit is '.$maxsize.' bytes</div>

                <div>File '.$_FILES['userfile']['name'].' is

                }

        }

        else

            $msg="File not uploaded successfully.";

 

    }

    else {

        $msg= file_upload_error_message($_FILES['userfile']['error']);

    }

    return $msg;

}

 

// Function to return error message based on error code

 

function file_upload_error_message($error_code) {

    switch ($error_code) {

        case UPLOAD_ERR_INI_SIZE:

            return 'The uploaded file exceeds the upload_max_filesize directive in 

 

php.ini';

        case UPLOAD_ERR_FORM_SIZE:

            return 'The uploaded file exceeds the MAX_FILE_SIZE directive that was 

 

specified in the HTML form';

A) what exactly does this have to to do with the forum section you posted in - PHP Applications Drupal, Joomla, Zen Cart, osCommerce, MediaWiki, etc.?

 

B) given that you just parroted a reply in another thread where someone didn't ask an actual question in their post, what exactly is the question or problem you have with this code?

 

C) you have been told in other threads to post code using the forum's


bbcode tags.

This thread is more than a year old. Please don't revive it unless you have something important to add.
