I have a form, getting values by $_POSTaccording to name that's okay. But how can I get value of not input. For example;
<b name="name1" value="1001">Phones</b>
How can I get 1001 by $_POST according to name="name1". Trying $_POST['name1'] but can't get.
What you have isn't a form input:
<b name="name1" value="1001">Phones</b>
The entire HTML isn't sent to the server in a form post, only form values are. So you need to have that in a form input. For example:
<input type="hidden" name="name1" value="1001" />
Then you don't need that information in your <b> element:
<b>Phones</b>

I have the following code snippet of my fields I have in my form:
<input id="username" type="text" placeholder="E-mail Address" value="" name="username"></input>
This is what I have in my input field. Is there anybody who will tell me how to get input values to the field using a url? e.g https://mysite?username=ken and it will show "ken" in the input field?
In your HTML, add the input field like this:
<input type="text" name="username" value="<?php echo htmlspecialchars($_GET['username']); ?>" />
Basically, the value attribute of the text field needs to be set to:
<?php echo $_GET['username']; ?>
The code right above this is how you would output a get variable in php whether you are putting it in a text field or not.
To access get variables, always use:
$_GET['variable_name'];
Then you can assign it to variables or pass it as a function parameter.
**However, I strongly do not recommend passing sensitive information like usernames and passwords through GET variables. **
First off, users could change the URL hence changing the variable. They could also accidentally share the URL with someone and that could give someone else access to their account. I would recommend that you create a cookie on their machine that is set to a random ID, and then in a MySQL database, associate that ID with a username so that you know the user can't accidentally share their account or change their username through the URL.
You can do it like this, make an isset in your php form input that can catch your ken variable from GET post, never forget the method="get" inside the form tag and if you are planning on submitting on the same page you can use action="<?php echo $_SERVER['PHP_SELF']; ?>" inside your form tag.. hope this helps, here is your code.. ^_^
<form id="form" name="form" method="get" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<fieldset>
<p>Input</p>
<div>
<input type="text" name="nameoffield" id="nameoffield" value="<?php if(isset($_GET['ken'])){echo $_GET['ken'];} ?>"> <br />
</div>
</fieldset>
<div>
<button type="submit" value="Submit" name="submit">
Submit
</button>
</div>
</form>
The <input> tag and other fields of form must be in a <form>tag.
<form action = "https://mysite" method = "get">
<input id = "username" type = "text" placeholder = "E-mail Address" name = "username" value = "<?php echo $_GET['username']; ?>" />
</form>
In the above code, form tag specifies that the method of submission is 'GET' and the action that will be taken on submission is URL to which your form data will be submitted and processed.
Now assuming that your form is in the same URL to which you are submitting your form, you will get the GET value in the same page (or URL), so in the input text field set the value which is obtained by GET method and use it.
All the GET key-value pairs are stored in an associative array $_GET from which you can access the value of a given key by using that as the index of the array.
e.g. Key is username in this case, so to get the value of the username, $_GET['username'] was used.
I have a set of input boxes and you can add more and more sets of these forms if you click the add more button. In my form I can submit data and I have got it to show up when you reload the page, when the page shows it it also adds a value into a hidden form in case the user updates this information.
However, how can I see all the sets of data which do not have a hidden form value? And all the sets with do have a hidden value so I can do different things to them.
Here is my code:
HTML:
<form>
<div class = "fieldset-1">
<input type="text" id="Name1" name="name[]">
<input type="hidden" id="id1" name="id[]">
</div>
<div class = "fieldset-2">
<input type="text" id="Name2" name="name[]">
<input type="hidden" id="id2" name="id[]">
</div>
</form>
PHP:
$data = $_POST;
extract($data, EXTR_PREFIX_SAME,"br");
//Prints The Variables To Make Sure They Are Correct
print_r($id);
$name = preg_replace("/[^a-zA-Z- ]/", "", $name);
print_r($name);
You have all the post data in a $_POST. It doesn't depend on field's type. The only thing matters — field's name.
The reason why you can't see it with your code is that you do
$name = preg_replace("/[^a-zA-Z- ]/", "", $name);
For what, btw? preg_replace is for string, $name here is an array (cause your form field has a name name[]), so function fails, and you lost your data.
And don't ever use extract, it's considered harmful.
I am try to get the value of the input field with a custom attribute I have created using PHP. This is my code:
<form action="uploadform.php" method="post">
<input type="text" name="email" id="email" mynewattribute="myemail">
<input type="submit" name="submit">
</form>
//uploadform.php
<?php
//I know $name = $_POST['email']; will give me the value but I would like to get the value of the input field with "mynewattribute" and not name. Is it possible?
?>
The web browser doesn't know what to do with your custom attribute, so will simply ignore it. The only data sent when you submit the form is the values of "successful" elements. So your custom data will never be sent, and can never be read by the receiving script.
The best place to put such data is into hidden input fields. One possibility is to use names with square brackets in, which PHP automatically converts into arrays. e.g.
<input type="text" name="email[value]">
<input type="hidden" name="email[magic]" value="true">
Populates an array like this:
$_POST['email']['value'] = '';
$_POST['email']['magic'] = 'true';
I have a live search form on the site that does two things. If it gets any results it displays them, and if not, the visitor can send an email.
There are two input type fields
<input type="hidden" name="myField" id="myField" value="" />
Email: <input name="email-index" id="email-index" type="text" /></b>
In the email field, the visitor inputs the email. And in the value of the hidden field, i want the search query to be passed from the query.
The search query results are displayed one div before this form with
<!-- Results -->
<h4 id="results-text"> <b id="search-string"></b></h4>
where search-string is replaced with the query.
I have put this into jquery
var hidden = "search-string";
$('input[name=myField]').val(hidden);
but nothing really happens, i get an empty output.
Thank you for your help!
If you have $_GET['search-query'] parameter, just output it to input field:
<input type="hidden" name="myField" id="myField" value="<?php echo $_GET['search-query']; ?>" />
It is because you do not actually get anything from jquery.
Change your script to:
var hidden = $("#search-string").text();
$('input[name=myField]').val(hidden);
I'm new to PHP but I'm working on an email script for an order form.
I have all the values and what not in a form, with a text element that is span-ned for javascript access client side.
What I need to do is also access these span values when I POST.
HTML:
<form name="myform" action="submit.php" method="post">
<strong>Price:</strong> $<span id="SMP">11.99</span>
<strong>Price:</strong> $<span id="SDP">11.99</span>
<strong>Price:</strong> $<span id="YTP">11.99</span>
<strong>Price:</strong> $<span id="SDP">11.99</span>
//bunch of input form code i truncated for readabilty
</form>
You can't do that. The POST array will only contain what you post via input fields. Easiest thing for you to do would be to have some hidden inputs with your values in them
<input type="hidden" name="prices[0]" value ="11.99">
<input type="hidden" name="prices[1]" value ="11.99">
<input type="hidden" name="prices[2]" value ="11.99">
This will be available in your $_POST array. You can access it like
$value1 = $_POST['prices'][0];
Or just iterate it through as an array
You can't. You'll have to add some hidden inputs, and modify them from Javascript, to get them server-side. PHP can't access to the HTML, and only inputs elements are posted.
