Image Upload and Cropping with PHP and jQuery

Step 1: First we will include all necessary jquery plugin and library files.We will keep all below files in head section of index.php file.








Step 2:We will Create div to show image and option to change image.


Here i am showing default.jpg image file for as a default image.

Step 3: Now we will create model box to upload and crop image.



Step 4: Now will write some jquery code to show the model box when we will click change pic button.

jQuery('#change-pic').live('click', function(e){
		e.preventDefault();
		
		jQuery('#changePic').show();
		
	});

Now you can show image upload bootstrap modal box on click of Change Image.

Step 5: Now we will use jQuery Ajax form plugin for form submitting and show the image for crop process on bootstrap modal box.

jQuery('#photoimg').live('change', function()	
{ 
jQuery("#preview-avatar-profile").html('');
jQuery("#preview-avatar-profile").html('Uploading....');
jQuery("#cropimage").ajaxForm(
{
target: '#preview-avatar-profile',
success:    function() { 
        jQuery('img#photo').imgAreaSelect({
        aspectRatio: '1:1',
        onSelectEnd: getSizes,
    });
    }
}).submit();
});

You can get image all parameters on 'success' call back function.

Step 6: Now we will cropped image and call save Ajax method to save image on hard disk storage.


//fucntion for get image cropped co-ordinate
function getSizes(img, obj)
	{
		var x_axis = obj.x1;
		var x2_axis = obj.x2;
		var y_axis = obj.y1;
		var y2_axis = obj.y2;
		var thumb_width = obj.width;
		var thumb_height = obj.height;
		if(thumb_width > 0)
			{

				jQuery('#hdn-x1-axis').val(x_axis);
				jQuery('#hdn-y1-axis').val(y_axis);
				jQuery('#hdn-x2-axis').val(x2_axis);
				jQuery('#hdn-y2-axis').val(y2_axis);
				jQuery('#hdn-thumb-width').val(thumb_width);
				jQuery('#hdn-thumb-height').val(thumb_height);
				
			}
		else
			alert("Please select portion..!");
	}
	//call on crop iamge button
jQuery('#btn-crop').live('click', function(e){
	e.preventDefault();
	params = {
            targetUrl: 'profiles/saveAvatarTmp/',
            action: 'profiles_controller_saveAvatarTmp',
			x_axis: jQuery('#hdn-x1-axis').val(),
			y_axis : jQuery('#hdn-y1-axis').val(),
			x2_axis: jQuery('#hdn-x2-axis').val(),
			y2_axis : jQuery('#hdn-y2-axis').val(),
			thumb_width : jQuery('#hdn-thumb-width').val(),
			thumb_height:jQuery('#hdn-thumb-height').val()
        };
		saveCropImage(params);
	});
	//make ajax request to PHP for save image
function saveCropImage(params) {
    jQuery.ajax({
        url: siteurl + params['targetUrl'],
        cache: false,
        dataType: "html",
        data: {
            action: params['action'],
            id: jQuery('#hdn-profile-id').val(),
			 t: 'ajax',
								w1:params['thumb_width'],
								x1:params['x_axis'],
								h1:params['thumb_height'],
								y1:params['y_axis'],
								x2:params['x2_axis'],
								y2:params['y2_axis']
        },
        type: 'Post',
       // async:false,
        success: function (response) {
				jQuery("#changePic").hide();
				jQuery(".imgareaselect-border1,.imgareaselect-border2,.imgareaselect-border3,.imgareaselect-border4,.imgareaselect-border2,.imgareaselect-outer").css('display', 'none');
				
				jQuery("#avatar-edit-img").attr('src', response);
				jQuery("#preview-avatar-profile").html('');
				jQuery("#photoimg").val();
				AlertManager.showNotification('Image cropped!', 'Click Save Profile button to save image.', 'success');
				
				
        },
        error: function (xhr, ajaxOptions, thrownError) {
            alert('status Code:' + xhr.status + 'Error Message :' + thrownError);
        }
    });
	}
	
	

Step 7: We will define controller/action method in profile.php.

/*********************************************************************

		list($txt, $ext) = explode(".", $name);
		if(in_array($ext,$valid_formats))
		{
		if($size<(1024*1024)) // Image size max 1 MB
		{
		$actual_image_name = 'avatar' .'_'.$userId .'.'.$ext;

		$res = $this->Profile->saveAvatar(array(
						'userId' => isset($userId) ? intval($userId) : 0,
												'avatar' => isset($actual_image_name) ? $actual_image_name : '',

		//mysql_query("UPDATE users SET profile_image='$actual_image_name' WHERE uid='$session_id'");
		echo "";
		}
		else
		echo "failed";
		}
		else
