Refrence I used for this http://simplehtmldom.sourceforge.net/

Here I can Get all HTML elements with that code.And I want to modify the Same HTML element with Updated Text.But I don't get any reference from anywhere.Please is my page screenshot.

If I change something in that h3 textbox it will change in about.php <h3>New text</h3> How can I do this If anyone knows the solution Please help me to get out of this problem.Thanks in advance.

Can you reduce your problem to a simple statement with a small amount of reproducible code? Sounds like all you want is <script>$(function() { $("#h3").val("xxx"); }</script>. Please read this minimal reproducible example — fdomn-m

I will show you for the first one $html->find('meta[name=keywords]'),You have to use a function __set from simplehtmldom, I am taking name of textarea as formss

foreach($html->find('meta[name=keywords]') as $element) {

$element->__set("content", "$_POST['formss']");

}

Please use different class or id for textarea, in a page there can be one meta keyword or title, but it can contain many h3 or h4 or h5. So use a for loop for that and it will make it easier for you. One more thing, why have you used $dom = file_get_contents($id); $html = file_get_html($id); two loading functions they will load the same thing and make your php execution slow.

May I know similarly how can I Set content for title

Kumar Over a year ago

First get title in a variable as you have done, and then use innertext instead of content in __set function

Kavya Shree Over a year ago

If multiple H3 tags is present in the webpage how can i set content?? Is there any way to find nth h1 tag and set content

Kumar Over a year ago

You can use find function like find("h3",n) where n is number of h3. remember that find function create an array and than save all dom element to their respective position for a web page
