I want to create a hidden field in my HTML page, all good, just a simple <input> field. Then, I'm trying to read the value of that input field as the page loads the first time, so the closest I've gotten to that is using a $_GET statement. I'm simply trying to echo out the value so that I can see that it's working like such:
<input type="hidden" name="selection" value="fixtures">
<?php
echo $_GET['selection']
and that just gives me nothing, if I try:
echo "<h1>$_GET['selection']</h1>
then I get 0.
Question is - what <form> parameters you have? Did you submit form? Simples example for it will be:
//form.php
<form method="GET" action="next.php">
<input type="hidden" name"selection" value="fixtures" />
<input type="submit" name="submit_btn" value="Send" />
</form>
//next.php
echo '<h1>'.$_GET['selection'].'</h1>';
You can achieve same thing with:

I'm currently working on at the displaying of information from a database. I was making a summary site where you can only see the important things of a table. After that i made the first element as an <input type="submit"> in a <form>, so u can click it and come to the detail site. My problem is now: The value of this input type has to be my ID, so i can query correctly on me detail site. I was wondering if it is possible to use something like a placeholder, so that the ID is the value, but on the input type is written other text.
My input:
<form method="post" action="Details.php">
<input type="submit" placeholder = "test" name="Overview" onclick="parent.location='Details.php'" value="<?php echo $data[$i1]; ?>">
</form>
How it currently looks
I want it that the input type still has the same value, but is displaying on the website something else like "test".
Greetings!
No, but buttons can have different values and labels.
<button name="foo" value="bar">baz</button>
Since you are using a form-tag per row, you can add a hidden input-field in the form and set the value of the submit-button to whatever you like.
<form method="post" action="Details.php">
<input type="hidden" name="id" value="<?php echo $data[$i1]; ?>" />
<input type="submit" name="Overview" value="test" />
</form>
I have a form located at a url containing get parameters,my form is also using this method.When the form is submitted it rewrites the previos get parameters.
Is there a simple way to rewrite only my form parameters?
I have in mind a Javascript solution ,however I want to know if there is a simpler way?Using HTML/PHP perhaps?
As far as I know, u u are not interested in using JS, then using form's hidden element is only way u have like this-
<form action="demo_form.asp">
First name: <input type="text" name="fname"><br>
<input type="hidden" name="country" value="Norway">
<input type="submit" value="Submit">
</form>
<p>Notice that the hidden field above is not shown to a user.</p>
The question is how u can use it with PHP, right?
The solution is here-
//In PHP
if( isset($_GET['fromPerson']) )
{
echo $fromPerson;
}
So combined HTML and PHP code will be like this (assuming a get element from prevous page is named fromPerson)-
<form action="demo_form.asp">
First name: <input type="text" name="fname"><br>
<?php
if( isset($_GET['fromPerson']) )
{
echo '<input type="hidden" name="country" value=".$_POST['fromPerson'].">';
}
?>
<input type="submit" value="Submit">
</form>
Lets say you get a parameter p1 from a get request, it should look like this:
http://server.com/?p1=123
In your form, you can add hidden fields that would have the same effect when you submit, like this:
<form method="GET">
<input type="hidden" value="<?php echo $_GET["p1"]; ?>" name="p1">
</form>
That way you can resend the variables as many times as you need.
I'm not sure I understand your question... Can you post your code?
I assume you mean something like this?
in index.php
<input type="hidden" name="id" value="<?php echo $id; ?>" />
in return.php
Edit
I am very new to php, I am having a problem passing data from textbox to a php variable to use it in an anchor tag. Below is the code i am using.
<form id="searchform" action="fetchvalues.php" method="get">
<input name="q" id="q" type="text" />
<input name="searchbutton" id="go" type="submit" value="" />
</form>
I want to pass value from searchbutton to anchor tag
Hello"
If you are using jquery in your project and want to do this on the front end, you can do:
<a id="someLink" href="http://www.example.com/?q=var" target="_blank">Hello"</a>
$('#someLink').attr('href', "http://www.example.com/?q=" + $('q').val());
With php you'd only be able to set the entered value of q on a post. (meaning when someone submits the form)
i.e.
Hello"
IF you need to populate the link href without a page refresh, you'll need to use javascript, if you want it to be populated after a form post, you can use php.
Be aware though that the link would need to be on the page set in your forms action attribute to populate the link
You should be aware that you take precautions when echoing out form submissions, however the level of questions suggests you've got more to learn before that. (No offense intended)
<form id="searchform" action="fetchvalues.php" method="get">
<input name="q" id="q" type="text" />
<input name="searchbutton" id="go" type="submit" value="" />
</form>
On your fetchvalues.php page
<?php
$val = $_GET['q'];
?>
then
Hello
You can do like this
<?php
if(isset($_REQUEST['searchbutton']))
{
?>
Hello
<?php
}
?>
I have a form on an HTML/PHP page.
I have the same exact code on other pages on the site, and it works fine. I cannot figure it out.
Form:
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input name="prize_id" type="hidden" value="<?php echo $prize_id; ?>" />
<input name="ContestEntry" type="submit" class="submit" value="Enter me in the Raffle!" />
</form>
I looked at the HTML source code, and the action populates the correct page, and $prize_id populates the correct info in the value.
PHP:
if(isset($_POST['ContestEntry'])){
//...code to enter data into form, irrelevent since it won't post anything anyway.
}
else {
echo 'Nothing posted from form';
}
"Nothing posted from form" always shows, and no data is being entered into the database. I've tried changing the form name to 5 different things, thinking maybe there was a conflicting name somewhere, but nothing works.
Any ideas?
If all you need to achieve is check whether the form is submitted or not, it's better to check that the request type is a POST:
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
// Process form
} else {
// Nothing posted!
}
Also change your submit button to:
<button type="submit">Submit</button>
and see what happens
The code you posted actually works for me.
But, if you still can't get it working, I would try checking to see if prize_id is set rather than the button. The PHP script is executed when the form is submitted.
Also, I would recommend that you don't use $_SERVER['PHP_SELF'] as the form action. According to https://stackoverflow.com/a/14093363/3593228, that can make it easy for attackers to insert malicious data. Instead, leave the action empty.
The if Condition is not working because you put it on Button, instead of this just make an hidden field in the form to check form is submit or not like as you already have one. Or make new for this form.
<input name="prize_id" type="hidden" value="<?php echo $prize_id; ?>" />
Consider adding what you're looking for as another hidden field:
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input name="prize_id" type="hidden" value="<?php echo $prize_id; ?>" />
<input name="ContestEntry" type="hidden" value="Enter me in the Raffle!" />
<input type="submit" class="submit" />
</form>
<form action="">
<input placeholder="SEARCH" name="search_input" type="text"/>
<input type="submit" name="search_submit"/>
</form>
If people search by "Keyword Item" I want URL will be http://mydomain.com/search?keywords=Keyword%20Item
How can I do it? I know needs configure in form action, get etc.
Thanks in advance.
Update
When I am trying with this code
<form action="http://search.golfoutletsusa.com/search?" method="get">
<input placeholder="SEARCH" name="Keywords" type="text"/>
<input type="submit" name="search_submit"/>
</form>
The URL is: http://search.golfoutletsusa.com/search?Keywords=85&search_submit=Submit+Query
I just want "&search_submit=Submit+Query" will be removed from URL.
<?php echo $_GET["keywords"]; ?>
You will need to change the name of the text field from search_input to keywords though.
You should also consider using an id attribute along with the name. And as the other answer says, form action and method should be set correctly.
Solution:1
You can add the following code at the top of your search.php (or, whatever the processor file):
<?php
if(isset($_GET["search_submit"]))
{
$keywords = $_GET["Keywords"];
header("Location: search.php?Keywords=$keywords");
}
?>
OR
Solution:2
You can omit the name of submit button if it is not really necessary to give it a name. So instead of
<input type="submit" name="search_submit"/>
just use
<input type="submit" />
Set action of the form to search.php and method to get.
Then change the name of your input element to keywords.
But still the url won't be - http://mydomain.com/search?keywords=Keyword%20Item
It will be - http://mydomain.com/search.php?keywords=Keyword%20Item
Simply put everything in the form properties, only you have to select a file which will receive all this, /search will not suffice:
<form action="search.php" method="get">
<input type="text" name="keywords" placeholder="SEARCH" />
<input type="submit" name="submit" />
</form>
EDIT: In the search.php file you would get the variable contents with the get global variable like this:
$search_query = $_GET['keywords'];
After that you simply write the rest of the code to do the search... Note that this would lead to an URL like http://www.example.com/search.php?keywords=query
