to the user’s profile page. Most important thing to be considered is the size of uploading file, because some users try to upload the photo of size 4 MB. But we don’t need so much

of clarity and the actual size allocated for profile image will only be 250*200 size or lower in dimension and larger photo size will acquire our server space. So we have to reduce the file size, size of the file is directly proportional to the quality of the image.

i.e., As photo size is reduced then quality of photo also gets decresed

 

Database

Create a table “tab” with two fields “id”, “filename”. id is auto increment.

Select Code
1
</p> <p>CREATE TAB `inter`.`tab` (<br /> `id` INT( 10 ) NOT NULL AUTO_INCREMENT ,<br /> `filename` VARCHAR( 1000 ) NOT NULL ,<br /> PRIMARY KEY ( `id` )<br /> ) ENGINE = INNODB;</p> <p>

index.php

Select Code
1
</p> <p><?php<br /> if(isset($_POST['submit']))<br /> {</p> <p>// $pic is the filename of the file<br /> $pic=($_FILES['photo']['name']);</p> <p>$filename = stripslashes($_FILES['photo']['name']);<br /> $targett="ques/".$filename;</p> <p>//This is your source file path<br /> $source_file = $_FILES['photo']['tmp_name'];</p> <p>//To get the image width and height if you want to resize the image with a perfect ratio and etc..<br /> list($img_width,$img_height) = getimagesize($source_file);</p> <p>//Create a new true color image<br /> $im = @imagecreatetruecolor($img_width, $img_height) or<br /> die('Cannot Initialize new GD image stream');</p> <p>//Create a new image from file or URL<br /> $img_source = imagecreatefromjpeg($source_file);</p> <p>//Copy and resize part of an image with resampling<br /> imagecopyresampled($im, $img_source, 0, 0, 0, 0, $img_width, $img_height,$img_width, $img_height);</p> <p>//Output image to browser or file<br /> $uu=imagejpeg($im, "ques/$filename", 20);<br /> move_uploaded_file($uu, $targett);</p> <p>$query1=mysql_query("insert into tab values ('$uu')");<br /> }<br /> ?><br /> <html></p> <p><body><br /> <form action="<?php $_SERVER['PHP_SELF'] ?>" method="post" enctype="multipart/form-data"><br /> Input Photo:<input type="file" name="photo" size=35 /><br /><br /><br /> <input type="submit" name="submit" /><br /> </form><br /> </body><br /> </html></p> <p>
