    <p>I am making a upload form inside PHP. Though I want the form to upload a thumbnail that is exactly, lets say, 100px high and 100px width. The form has to rescale the tumbnail without stretching the image, but by removing a part from the image. I prefer to do this with 100% php and the most simple script. I already have made my upload form and I only want to know how to make this auto-crop system with my tumbnails.</p> <p>I really hope you can help me out and I want to thank you in advance.</p> <p>My script already uploads a image with a thumbnail:</p> <pre><code>if( $imgtype == 'image/jpeg' ){ $filetype= '.jpg'; }else{ $filetype= str_replace ( 'image/', '', $imgtype ); } $path= 'images/' . md5( rand( 0, 1000 ) . rand( 0, 1000 ) . rand( 0, 1000 ) . rand( 0, 1000 ) ) . '.jpg'; $thumb_path= 'images/thumb_' . md5( rand( 0, 1000 ) . rand( 0, 1000 ) . rand( 0, 1000 ) . rand( 0, 1000 ) ) . '.jpg'; $imgsize2= getimagesize( $imgtemp ); $width= $imgsize2[0]; $height= $imgsize2[1]; $maxwidth= 1281; $maxheight= 721; $allowed= array( 'image/png', 'image/jpeg', 'image/gif', ); if( in_array( $imgtype, $allowed ) ){ if( $width &lt; $maxwidth &amp;&amp; $height &lt; $maxheight ){ if( $imgsize &lt; 5242880 ){ if( $width == $height ){ $case=1; } if( $width &gt; $height ){ $case=2; } if( $width &lt; $height ){ $case=3; } switch( $case ){ case 1: $newwidth= 100; $newheight= 100; break; case 2: $newheight= 100; $ratio= $newheight / $height; $newwidth= round( $width * $ratio ); break; case 3: $newwidth= 100; $ratio= $newwidth / $width; $newheight= $height * $ratio; break; } switch( $imgtype ){ case 'image/jpeg'; $img= imagecreatefromjpeg( $imgtemp ); $thumb= imagecreatetruecolor( $newwidth, $newheight ); imagecopyresized( $thumb, $img, 0,0,0,0, $newwidth, $newheight, $width, $height ); imagejpeg( $thumb, $thumb_path ); break; case 'image/png'; $img= imagecreatefrompng( $imgtemp ); $thumb= imagecreatetruecolor( $newwidth, $newheight ); imagecopyresized( $thumb, $img, 0,0,0,0, $newwidth, $newheight, $width, $height ); imagepng( $thumb, $thumb_path ); break; case 'image/gif'; $img= imagecreatefromgif( $imgtemp ); $thumb= imagecreatetruecolor( $newwidth, $newheight ); imagecopyresized( $thumb, $img, 0,0,0,0, $newwidth, $newheight, $width, $height ); imagegif( $thumb, $thumb_path ); break; } if(empty($errors)) { move_uploaded_file( $imgtemp, $path ); $upimage = "Image is successfully uploaded."; } } else{ $errors[9] = "The image you just uploaded does not meet the requirements. Your picture is too large. "; } } else{ $errors[10] = "The image you just uploaded does not meet the requirements. It is a forbidden extension."; } } else{ $errors[11] = "The image you just uploaded does not meet the requirements. It is a forbidden extension. Type: $imgtype, $image, $imgsize, $imgtemp, $name"; } if(empty($errors)) { move_uploaded_file( $imgtemp, $path ); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
