I am using the code below:
<form>
<textarea cols="50" rows="4" name="link"></textarea>
<textarea cols="50" rows="4" name="notes"></textarea>
<input type="submit" value="Submit">
</form>
It creates two text boxes and I was wondering how to get them from this into a different html file's body code? I think I would need PHP.
At the end I would just want it to display a message saying "Complete" and in a html file e.g code.html in the tags it would have the contents of the two text boxes seperated by one line.
Regards!
Sounds like you would need PHP to receive the data.
See this for a basic form that posts to a PHP page.
you most use php html like this:
echo '<form id="form1" name="form1" method="post" action="">'.
'<p>PASWORD<br>'.
'<input type="text" name="name0" id="text" /><br><br>'.
'<p>BACKLINK<br>'.
'<input type="text" name="name" id="text" />'.
'<br>;'.
'<input type="submit" name="Enter" id="Enter" value="Enter" />'.
'</form>';
and use if for run html
if ($_POST['name0']>''){
your code
}
To accept input one one page and display it on another will require PHP. The general idea:
The HTML form page:
Contains you HTML form where the user enters and submits their input. The data from the form is sent to the PHP processing script. We'll assume you use the POST method.
The PHP processing script:
Contains code to read the POST values and sanitize them. This means you want to check for HTML you don't want, script tags, etc - anything you don't want. In this case, the user will be displaying this code to themselves, so they can't really harm another user. However, it's something important to keep in mind. The rule of thumb - never trust user input - always check it and clean it. Now that the PHP script has read and cleaned the data, you want to display it.
The PHP display script:
Contains the HTML of the page and PHP code to display the values you captured in the PHP processing script.
Other notes:
The PHP processing and display scripts can live in the same file. You will have to process before you display. Alternately, you can run the processing script and then include the display script. Both will work.

I'm trying to create a cookie for a web page. The cookie value will vary based on the users name. Does PHP have an input type function? I just want to add an input field to the page an then the PHP will use that to define the users name for the page. I have the create cookie code, just can't figure out how to get the name from the screen and insert it to the cookie code. Appreciate any suggestions. This is on a WP website.
Not natively because php does not execute in browser, it executes on your server, but it can be used to write an HTML input.
The syntax would look something like this:
echo '<input type="text" name="myinput">';
or
?>
<input type="text" name="myinput">
<?php
You would then use a form post, CURL, or AJAX function to send the data back to the server where a second PHP script would process the input.
That said, it would help to post your create cookie code, since you may not even need to send it back to the server, but just handle it all in the browser using Javascript in which case your submit button only needs to pass the input to a Javascript function instead of posting it.
Is this something you are looking for?
Here it just takes the value user input from the browser and set it as a cookie
<?php
if(isset($_POST['name']) && !empty($_POST['name'])){
setcookie('setcookie_name',$_POST['name']); // setting cookie
}
?>
<form action="" method="post">
<input name="name" value="" placeholder="Enter your name" />
<input name="submit" type="submit" value="Submit"/>
</form>
I have a html page where the user can input some text, it is then posted to a php file and then stored in a database.
<form action="postphp.php" method="post" enctype="multipart/form-data">
<center><input id="postTitleStyle" type="text" name="title" size="100" maxlength = "180" ></center>
<center><textarea id="postTextStyle" name="Text" rows="10"cols="96" maxlength = "40000"><?php echo $text;?></textarea></center>
<center><input id="postTagStyle" type="text" name="tags" size="100" maxlength = "900" ></center>
<center><input type="submit" class = "Post2" value="post"></center>
</form>
Above is my current code for posting the data in the text field to a php file. I want to be able to click a button that when clicked will not go to the php file it will be stored and then when the user clicks the submit button it is posted. For example the user clicks it, a one is stored and then sent later when the user clicks the submit button after they are finished filling in other details. Is this possible?
P.S. I want to avoid Javascipt as much as possible for the moment, so if there is a non-java way of doing it then it would be much appreciated.
Many thanks, Jack.
There are two easy solutions to this problem without using Javascript. I'm assuming by your wording that you can currently post a form, but you don't know how to do so without leaving the current page. That's what I'll be answering below, but please note that there is no way to post a form without reloading at all without Javascript.
Solution 1: Put the PHP code into the same page the form is on and change the form tag to: <form action="" method="post" enctype="multipart/form-data">
A blank action field will cause it to run the PHP on the current page. You will likely need to look into using isset($_POST['submit']) in PHP, which will check whether the submit button has been clicked on before running that particular PHP code. You can read more about that HERE.
Solution 2:
In the postphp.php file that's currently linked to in your action field of your form, you could use a PHP header that will redirect the user after the PHP code is ran.
E.g.
<?php
{All your form processing code goes here}
header('location: my_form_page.php');
?>
In this example, my_form_page.php is the page on which your form is on. You can read more about headers in the answer of THIS question.
Hopefully this helps a bit.
$title = $_POST['title'];
$text= $_POST['text'];
$tags = $_POST['tags'];
mysql_query("INSERT INTO `table_name` (`colname1`,`colname2`,`colname3`) VALUES ('$title,'$text','$tags')");
$id = mysql_insert_id();
if($id){
echo "inserted";
}else{
echo "Not inserted";
}
For this you need to use Ajax (JavaScript will be used) because you need a button which send data to server without form submission and page reload it can be easily achieved using Ajax.
I am looking for a bit of code to do the following:
A form containing a single text field and a submit button, must send the value of the text field to a landing page that automatically counts how many html tags that this page contains.
E.g. if the text field states stackoverflow.com, the landing page should say (H1 tags = 20) with many more parameters to come.
How is this done? I know how to make a form, but I do not know how to make it send its value to the landing page.
<form action="landingpage.php/" method="post">
The URL
<input type="text" name="cf_name">
<input type="submit" value="Submit">
</form>
This piece of code is a perfect answer to your question.
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="GET">
Type In Something: <input name="random-info" type="text" size="25">
<input type="submit" value="Submit">
</form> <br>
<?php
echo "You Typed: " . $_GET['random-info'];
?>
you get the method into the url, then you can use them on another page.
To access data from a form it depends on the method. Since your code shows a post message you simply access it in the php on the landing page by user $POST_['cf_name'].
To learn more you can check out:
http://w3schools.com/php/php_post.asp about the post method and http://w3schools.com/php/php_get.asp about the get method.
Also an invaluable source is php manual itself.
As far as counting the tags, not really sure what you are trying to achieve.
If you are counting the tags in the page you create, just make a variable and add to it each time you put that specific tag on the page.
Then you can put those values in a hidden field of the form to be passed into your landing page.
how can i pass parameters from an html page(map.html) to a php(createxml.php) without having to open the php page? Im incorporating googlemaps in html page(map.html) so i want the users to enter data on a form on the html page which will be sent to php(createxml.php) which in turn will connect to mySQL DB and create an xml format of the response the html page uses this xml output to create positions on the map since it contains longitude and latitude.
I have used the following code in the heading of the php page(createxml), but it shows the contents of php file for a brief moment redirecting me to map.html
Thanks for your time, i can post all the code if needed.
<meta http-equiv="refresh" content="0;url=http://localhost/map.html/">
It's quite simple with AJAX, using jQuery you don't have to know much about it :)
So simply import the latest jQuery Library.
Then you have your form:
<form id="my_form">
<input type="text" name="param1" />
<input type="text" name="param2" />
<input type="hidden" name="action" value="do_stuff" />
<input type="submit" value="Submit" />
</form>
and somewhere beneath that, you just paste this tiny javascript-function, which handles the submit of the form:
<script>
$('#my_form').submit(function(){
var post_params = $('#my_form').serialize();
$('#waiting').show();
$.post('the_page_you_are_on.php', post_params, function(data) {
$('#waiting').hide();
return false;
})
});
</script>
(The element (div, p...) with the id "waiting" could e.g. contain one of those fancy ajax loading images, but is not neccessary! :) If you want one to be shown, find one via google, set it as the background image of the #waiting-element and set its display to none (CSS)).
The function itself just calls the page you're on and then you've got the form variables in your post-array, so the top of your page could look something like this:
<?php
if(isset($_POST['action'])) {
switch($_POST['action']) {
case 'do_stuff' :
$param1 = $_POST['param1'];
$param2 = $_POST['param2'];
//do some DB-stuff etc.
break;
}
}
?>
I hope that helps!
It's a terrible idea, but because you don't want to use AJAX you could put the PHP in a frame and reload just that portion. Again, awful idea, but the closest you're going to get without using AJAX.
On a useful note though, AJAX is literally just one function in javascript. It's not hard at all to learn.
If you are just trying to pass parameters to a PHP page from the web browser, there are other ways to do it beyond 'Ajax'. Take a look at this page and view the source code (be sure to view the source of the included javascript file: http://hazlo.co/showlist.php?s=chrome&i=4e289d078b0f76b750000627&n=TODO
It uses an extremely basic method of changing the src of an image element, but passes information to the web server (PHP page) in the querystring of the image request. In this example I actually care about the results, which are represented as an image, but it sounds like you are just trying to pass data to the server, so you can return a 1 pixel image if you like. BTW, don't be fooled by the URL that is being used, a server rule is telling apache to process a specific PHP file when check it,GIF is requested.
You should play with it and use firebug or chrome's built in debugger to watch the requests that are being sent to the server.
You can't get any results from a PHP-script if you don't request it and process the output. If you dont't want to leave the current page, you have to use AJAX!
"but it shows the contents of php file for a brief moment" The reason is, that your browser first needs to load the entire page, then start the META-redirect. You don't need a redirect to load data from the server, but if you really want to, you should HTTP-headers for redirect.
Ok guys after hours of headache i finally found the solution! Basically i called my xmlproduce.php from inside my map.html, lemme explain so maybe will help others:
maps.html contained a googlmap API Javascript function which called my createxml.php called second.php
GDownloadUrl("second.php", function(data) )
what i did was i tweaked this call to second.php by adding some parameters in the URL like:
GDownloadUrl("second.php?strt="+ysdate+"/"+msdate+"/"+dsdate+"&end="+yedate+" /"+medate+"/"+dedate+"&id="+ide, function(data)
which is sending the parameters needed by second.php, so after that i made a small html form which called the script of googlemap api on the same file(map.html) to pass the parameters from the form to the GDownloadUrl i mentioned above, the code of the form is :
form method="get" action="">
IMEI: <input type="text" id="id" name="id" size="25" /> <br />
Start Date: <input type="text" id="ysdate" name="ysdate" size="4" value="2000" /> <input type="text" id="msdate" name="ysdate" size="1" /> <input type="text" id="dsdate" name="dsdate" size="1" /> <br/>
End Date: <input type="text" id="yedate" name="yedate" size="4" /> <input type="text" id="medate" name="ysdate" size="1" /> <input type="text" id="dedate" name="dedate" size="1" /> <br/>
<input type="button" value="submit" onClick="load()" />
</form>
afterwards i put extra constraints on the form for the values allowed.
Thanks everybody for the help, and you can always ask if somebody needs some clarification.
I have a index.html where I would like to submit some coordinates that can be passed upon to separate PHP file; where it could perform a query. I am new to this.
HTML:
Xmax<input type="text" name="Xmax" size="15">
Ymax<input type="text" name="Ymax" size="15">
<input type=SUBMIT name="submit" VALUE="Submit">
PHP query:
$query = "SELECT * FROM state WHERE LONG_HI<$_POST["Ymax"] AND LAT_HI<$_POST["Xmax"];
$result = mysql_query($query);
So is there a way to perform remote action from this HTML file to the specified PHP file?
Well, Forms can do the job. Is'nt it?
Yes
Either make an HTML form to accept the Xmax and Ymax parameters, and set the form action to the PHP file;
Or use AJAX to pass the data in the background and receive a response.
If both of these concepts are foreign to you, and you don't know JavaScript, get comfortable with the first option first.
Would you please describe in detail what you are about to do?
do you have a html form?
What kind of request do you do, clicking a link, sending the form?
The query does not contain any of the variables...
could you please post excerpts of the code? single lines are useless in most cases.
Regards,
Mario
use action attribute in FORM element to specify where the request will be sent to.
<form action="another.php" method="POST">
Xmax<input type="text" name="Xmax" size="15">
Ymax<input type="text" name="Ymax" size="15">
<input type=SUBMIT name="submit" VALUE="Submit">
</form>
You just add few line with your code because to transfer any variable value from one form to another page we have to use 'form' method. So, we have to add form tag with your code. Transferring of data from one page to another page (any type of page like php, jsp, aspx etc) is done by two methods mainly - one of them is Post and another one is Get.
Difference between both the method is quite simple. In Post method, data from one page to another page travels in hidden form whereas Get is basically used to transfer value by displaying it at url. Post method example: user-name and password, and Get Method: any query fired at Search Engine.
<form name="form" action="filename.php" method="POST" >
//Your Code
</form>
