Forms in HTML continued…

In the previous post we designed a good-looking form. Yes we did that (you should proudly smile for that). And now we’ll move a step further.

But before making any changes in the coding of our previous form, let me introduce you with my next post which will be a fantastic layout of a Home Page . So don’t miss it, it will be a whole FUN, I guarantee.

We can limit the user/applicant to enter only valid details in a form. For this we need to add some attributes inside <input> just like we have learnt to add type and name attribute. In the same manner we’ll add the following attributes-

required=”true” . In whichever field (by field i mean whether name or qualification or address or any field of your form) you use this property, that field will become mandatory to be filled in order to submit the form.

<tr><th>Name</th><th><input type="text" name="name" required="true"></th></tr>

I have implemented in only one field, you may apply to all (I am making changes in same form we designed in previous post).

placeholder=”Enter your name” . You may use this as-

<tr><th>E-mail</th> <th><input type="email" name="mail" required="true" placeholder="Enter your email"></th></tr>

I have used this placeholder in my email field, you may use in any field and can give any name in placeholder.

maxlength=” “ with this you may restrict the applicant to limit the text upto a certain length. This text could be his name or introduction or anything text-based.

Just like maxlength, max and min are used to limit numbers. These are also attributes inside <input>, so you can put nthem there and run the code. You may use this max and min even in date. Remember the pattern yyyy-mm-dd

<tr><th>DOB</th> <th><input type="date" name="dob" required="true" max=2020-10-19 min="2008-04-19"></th></tr>

QUERY STRING

Query String is the means to send information from one page to other through Uniform Resource Locator. In previous post we have seen how the information given by an applicant is shown in the url. Even the password is clearly visible. It means we cannot give sensitive information through this. But there is a way out. With the use of method = “post ” attribute inside <form>, we can hide the information. Please do it yourself and check the url after submitting the form.

Till now the information was loaded in the same page in which the form was displayed but if we want to send that information to some other page( this could be a html or php or any file which could be opened on browser), we can do so. This is done using action attribute inside <form> tag. We can give some name of other html file in the action and run the code. And be sure that the file whose name you are going to put in action is in the same folder. This time as soon as you will submit the form , you will be directed to that page whose name you have given in action. Let me quickly show you that line of code-

<form method="post" action="syntax.html">

By default method is get.

That’s it for this post. I have tried to keep this short and simple. But if you have any doubt share your problems here in comments. And follow this blog so that you may know about new posts.
