accept only number in input text box without using script

Question

How to allow only number in input text box

<input type="text" name="price" id="input-country" required placeholder="Enter Your Price" accept="number">

i used the above method but its not working when i use only allowed type in image input i use the following method

<input type="file" class="custom-file-input" accept="image/x-png, image/gif, image/jpeg">

this method works fine in same way how to allow only number and how to allow only text, and protect form SQL injection

Btw, if you really want to protect from SQL injection, I recommend this post: http://stackoverflow.com/questions/134099/are-pdo-prepared-statements-sufficient-to-prevent-sql-injection — Bluedayz, Aug 31 '14 at 07:21

If you are using HTML5 then use <input type="number">

If you realy wish to get rid of SQL injection Use this

You can use javascript like:

<input type="text" onkeypress="return event.charCode >= 48 && event.charCode <= 57">

The above code only accepts numbers.

If you want to use decimal number then you can use like:

<input type="text" onkeypress="return event.charCode >= 46 && event.charCode <= 57">

Try this code, maybe it will help.
