At the same time, it is practically possible for a site not to do without elements of the interface for the command field of the text input, buttons, switches and paraports. The stench is necessary for interfacing with koristuvach, to search the site for keywords, write comments, testify, attach photographs and work a lot of other similar speeches. Form it yourself to ensure the processing of data and data transmission to the server, de stinks are already being analyzed and processed. Also, if you are planning to work similarly on the site, you won’t be able to implement it without forms.

The form itself is created behind the help of the tag

Before editing data, the browser prepares information for the bet "im'ya=value", which is indicated by the name attribute of the tag or the other valid tag in the form, and the value is entered in the box or inserted in the form field after the key. After pressing the Submit button, a click of the form collector will appear, which will take away the information entered from the form, and then those who send the retailer will continue to work with it. How to form a form, sound the program, set action attribute tag

As the value of the action attribute, you can specify the same address email, doing yoga s keyword mailto: . When overpowered, the form will be launched mail program for the lockdown. With a security method in the browser, it is installed that it is not possible to correct the information entered in the form, it is not possible. For correct interpretation of the data, match the enctype attribute to the text/plain values ​​of the abstract

Browsers ambiguously treat this code. Firefox propagate the list relevant supplements for overstrength post (Fig. 1), Internet Explorer Vivede advance (small 2) and try to run the program, set in advance, Opera, like Firefox, will request a list of options suitable for editing the mail (small 3).

Rice. 1. Launching the program from Firefox

Rice. 2. Retarding Internet Explorer

Rice. 3. Select programs in Opera

In the process of navigating through the sites of Koristuvach, basically, there is no more clicking on to the forces schob peresuvatisya on the web pages.

HTML-forms are the most important elements of interaction that define the interactive part of the web site. One cannot live without them. Aja itself for their help, the main exchange between the server side is established.

Ale at the same time, form it with collapsible elements for the interface, with a great variety of functional components and text fields. To that, in this section, let's take a closer look at the main elements of the report, adding special respect to the practical їх zastosuvannya at the created site.

Moreover, the power supply of the robots with the MySQL data base will also be destroyed here. Oskіlki zastosuvannya forms in the stocks will be inconsistently connected with the interaction with the tables of the database. In some cases, the data entered by the clerks will be taken into account, which will be collected by the server at the hour of the request processing.
