Is there any way to refresh the data after I click the submit button? Currently as I click the submit button on my PHP page, there are changes to the database. But, I will have to refresh the page itself to see the updated result, which I think it is quite incompetent.
To add on, what I am doing is on a table form. So example,
1) 14 Dogs.
So after i edit 14 dogs to 13 dogs and submit, the changes are successful as seen in the database, but the value won't change unless I refresh the page. Thank you all.
Additional Info:
I'm using XAMPP, Microsoft Access.
in your script, instead of
code that outputs data from database
code that updates database
do
code that updates database
code that outputs data from database
I just changed the order. Hopefully its obvious why.
im assuming youre using a regular form, no ajax or frames.

I have a web page that loads all the data from a mysql database called datalist.php
From this page I can edit record by record with a button that redirects you to an editdata.php page adapted to the fid of the record.
Once edited as they want to see the changes, I don't redirect them to the main one letting them see the changes and simply clicking back or with a button they return to the datalist.php without any problem.
The button is this
echo "<p id='parrafo'><a style='padding:1px 20px'class='button rounded-0 primary-bg text-white w-0 btn_1 boxed-btn' href='javascript:history.back() '><--</a></p>";
PROBLEM
I added a search engine where the displayed data can be filtered.
When they use the search engine from datalist.php, I direct them to a page called search engine.php where, through a post method, I store what they are looking for in a variable and the data that users want appears.
But when they edit a filtered record, it is edited without problems, but when they go back, they return to the search engine.php and the message appears:
"Confirm form resubmission In order to display correctly, this web page needs the data you entered earlier. You can submit that data again, but that will cause the page to repeat all previous actions. Press Reload to submit the data and display the page.
Hit the page refresh button to resubmit the data needed to load the page."
Of course, if they update, they come back when the filtered data comes out.
Isn't there any way to store the variable used in the search so that when I go back I don't get this error or any solution??
simple! when user will submit form for that variable instead of making post request
option1: just use get request __url__?variable=... but this will not remember the variable when you go back
option2: store the variable in the cookie and just go to next page (eg. window.location.href = '...';). and in next page access the cookie from php.
If you are wanting to show the form to the user as a confirmation, but without the possibility of another post, then remove the form element and the button. Display all other boxes as they are (with the values populated from the POST array).
And display another message telling them that it has been successful.
You are using PHP, you can achieve this easily with it. If you are unsure, then post a short version of your code in a separate question.
That's the task I am currently facing:
Starting point: I have a form, which accepts data and saves it into the database.
What needs to be done: I need to include a button called "show data" (a different one than the "submit" button in the form, it can even be a clickable div), which will then display the data from the database on the same page, under the form. The button should also enable refreshing the list after new data was inserted into the form.
Now, if the data from the database had to be displayed on a different page, that could be handled easily with routing. However, for this particular task, I need to display the data on the same page.
My question: Is there a pure Laravel/PHP way to solve that problem? I am considering using AJAX (to which I am also new), but if there is some Laravel specific solution then I would prefer that.
The solution needs to work on localhost.
For PHP, without having any help from JavaScript, showing any changes to the database will require a browser refresh. On the front-end, you can use VueJS and Axios to help you with these requests, which do not require the browser to be refreshed.
I am tying to put some user data from the database using php.
The database contains so many record and i am displaying it using mysql_fetch_row() and this gives me the fields of first row.
Now the problem is a have two buttons namely next and previous. And when a click next the fields in the next row has to be obtained the they should be inserted into page without loading the page once again. I am facing problem with this.
I am using php for server side programming and html, css for client side programming.
I think that no one will give you the answer. Too many to write. You need to read about ajax (this is the technology that will allow you to do some action without page reloading).
You need to write javascript(you can use some library like jquery) function which will open some php page with the data that you want and then update your site.
Here you have some nice tutorial:

I am a newbie to programming. I have a PHP website which works as follows
Index Page - Search Results - Show a Product
The site user enters search critera on Index Page and the page is POSTed to Search Results page. From there, the site user clicks on a Product href that takes him to the Product Details. This is working fine till here.
The problem occurs when the user click the browser BACK button. The Search Result page comes up totally crashed and the user has to press F5/Browser Refresh to re-submit it. Any idea/technqiue that I can use to avoid this crash?
When a browser goes back to a page that comes from POSTing some data, the browser often times needs to re-POST the data in order to get the same page back. Since that can sometimes be bad (e.g. re-POSTing an order form), many browsers require the user to force a refresh with a warning.
You can generally use a GET instead of a POST form to avoid this.
An idea would be using GET for the method of your search form instead of POST (that apparently you are using). That way, even if going back in browser history, your server could re-supply its search results.
You would need the following:
change method="post" to method="get" in your search form
change every $_POST relating to the search form data to $_GET in your search form processing php file.
Of course, it could not work for your specific usecase. That's just an idea.
I want to create a page where people can insert some text, hit enter, and the text be stored in a MySQL database. I can do this, but I want to be able to load a page, enter a password, and see a list of all the info in said database, then whenever something is added to the database, it's added to the list on the page, without me needing to refresh the page or setup some javascript code to refresh the page every five seconds.
I believe Satya has it correct in suggesting that you use Ajax in order to refresh the data without refreshing the page. You can have it request updated information from a php script which queries your database for the data you wish to display, and then sets the elements on your page accordingly.
this is probably the best way for you to implement ajax calls using javascript
http://api.jquery.com/jQuery.ajax/
Or you an simly do it with the help of setInterval() function. You can call an html code in a div using
$('#id').html("<htmlcode></htmlcode>");
