Security Forms
On a normal Web forms you can "attack" using automatic scripts. Attacks are carried out by the robot into the forms found inserted meaningless data and sends the form. At the same time tests whether a form can be exploited for mass spam.
If you want to prevent your forms being misused, you can do so by pasting the image with the number into your form. See the pictures below this text. The number on the picture, the person filling out your form to overwrite in the designated field in the form. The accuracy of the code-the picture of us subsequently verified.
If you do not fit to your site we created images, you can create similar images themselves. The condition, however, is that the image you created will contain the same code number as they contain pictures below. Image created by the same name (e.g., rand01_01. gif).
Sample HTML code:Assuming that I want to use the first image rand01_01. gif, I must add the following code to the form's code:
<input type="hidden" name="CheckCodePicture" value="1" />
<input type="text" name="CheckCode" />
<img src="rand01_01.gif" />
Protect form by filling in the numbers from the image
