I am required to send data from an html page, via input elements to a php script and I cannot use ajax for some reason. How to accomplish this?
My code is something like this:
HTML:
First Name : <input type"text" name="first_name">
<br><br>
Last Name : <input type"text" name="last_name">
<br><br>
<button id="submit_btn">Submit</button>
Now, I want the javascript to be something like :
function redirect_from_here() {
close(); //close the current window
window.location='./phpfile.php'; //load the new page which will process the data sent to it.
}
My question is how do I send the value in the input elements in the HTML portion, as data to be processed, to the php script (phpfile.php in this case).
Please note that I prefer not to use html form for doing the job.
You are using HTML form as there are input fields in you code.
Inputs are part of a form and should be wrapped by a form element
Why using JS for submitting the form when you can use <form action='script.php'.. for that?
I suggest that you revise your requirements instead of trying to come up with a hackish way of how to send the data..
Just submit a form with action="phpfile.php"
if not interested with html,
then in the window location bind the values as a GET form method do

I want to make a post API call from a anchor HTML tag and URL will be included in the href.
How can i attach the body parameters.
<a href='http:/test_url:5002/api/GetFile'></a>
And in this I want to send the body parameters in the call as well.
I want to find a way to include this in the html tag itself, not in the javascript file.
Help will be appreciated.
Links are designed to GET a URL. You cannot make a POST request directly with them.
Use a form with a submit button instead.
Thats what forms are for. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form
Just create a form with a submit button. You can also specify if you want to open the requested URL in a new tab with the target attribute.
This is a way you could do it
<form method="POST" action="/api/PostFile">
<!-- with input in between -->
<!-- and a submit button-->
</form>
there's only one way for you to POST data with a link... you would need to wrap the code in a <form> and use that link to submit the form, for example:
<form id="frm" ation="http:/test_url:5002/api/GetFile">
<input type="hidden" name="param1" value="value_for_param1" />
...
...
</form>
any input can be used to append parameters to the <form>, as an example, the hidden is used
now, remember that you shouldn't use http:/test_url:5002 just minimize to /api/getfile or you would most likely get caught into CORS issues
I am creating a website backed by a database. I have created my forms that collect the information but now i need to read in the input from the form when user clicks submit and process it for mySQL. I am having my form action be a new page but I can't figure out how to read in value from the previous page. My Form code looks like this:
<div data-wrapper-react="true">
<span class="form-sub-label-container" style="vertical-align:top;">
<input type="text" id="first_3" name="q3_fullName3[first]" class="form-textbox validate[required]" size="10" value="" data-component="first" />
<label class="form-sub-label" for="first_3" id="sublabel_first" style="min-height:13px;"> First Name </label>
</span>
When user hits submit the action for this page is connect.php. I am not sure how to read in the value there. I tried this following command:
document.getElementById("first_3").value;
This just displays the code on blank html page for connect.php and not read in the values. The data from the forms needs to be processed into different tables if someone can help with that as well that would be great. Thanks
Form handling, in the way you are describing, is something you do server-side. PHP is handled on the server first where PHP tags can be evaluated to HTML, then this is returned to the browser. You would not handle form input from javascript, until after your PHP has done something with it. Here is a refresher: https://www.w3schools.com/php/php_forms.asp
<?php echo $_POST["q3_fullName3[first]"]; ?> would output the value into the HTML page allowing you to do something like this:
console.log("<?php echo $_POST["q3_fullName3[first]"]; ?>");
If you view source of the HTML, you will notice the PHP tag is gone and replaced with the form field value.
It sounds like you might want to get a book about PHP + MySQL since interacting with a database is a more advanced topic. I can recommend this one:

i created a Google Form and list down all the ID in each input type, and then created a localhost with the same ID,
The first thing i want to do is to save the values into a localhost and pass the values in the Google Form or set the values into the corresponding ID or Name in each input type in a new tab, is there a way to do this using ajax or jquery?
my form looks like this
<form method="post" action"">
<input type="text" name="FName">
<input type="text" name="LName">
<input type="Submit">
</form>
$post('https://docs.google.com/a/grabtaxi.com/forms/d/e/1FAIpQLSfjiuhFbURVavdNW82ofHG3gPpBUKkK2VATQQKmV-YKKrJ75Q/viewform'{FName:Fname,LName}function(){
window.open('https://docs.google.com/a/grabtaxi.com/forms/d/e/1FAIpQLSfjiuhFbURVavdNW82ofHG3gPpBUKkK2VATQQKmV-YKKrJ75Q/viewform');
});
i am trying to use the $.post() in jquery but it looks like i cannot set the values into the Google Form.
Any tips please... Thank You very much
You should wrap your javascript code inside a scipt tag. Then, you should bind the code to submit event, tha happened when you press the submit button.
<script type="JavaScript">
$('input[type=submit]').submit(
// here you should put your code
});
</script>
And check your code, you wrote $post instead of $.post mi sing the dot.
i have a textarea defined by an id
<textarea id='vegetable'> Tomato </textarea>
i have a button
<button type="button" onclick="MyFunction()">generate vegetable</button>
which trig a javascript in order to modify the content of the textarea
<script>
function MyFunction()
{
document.getElementById("vegetable").innerHTML = VegetableNameGenerator();
}
</script>
The problem is this php action :
<form action="{{ path('mypath', { 'myparam': ??? }) }}" method="post" >
<input type="submit" />
</form>
??? must be the content of the textarea (which is also known by the javascript code) but i don't know how to access it in twig.
I guess there are several way of doing that : jquery, dom, global variable twig... any syntax example would be great.
This is impossible in the way you're describing it.
When a request is made to the server, twig renders the page, then it is sent to the browser, and then javascript can run.
There are options for how to make this work:
Create a controller action which returns the rendered path when you call it using a GET request with the provided parameter. Then create an event listener on the submit button that blocks the submit process until it has retrieved the route via AJAX and modified the form's action attribute.
Redirect from your controller to the path you want displayed. myparam will be included in the post data, so you can redirect from your controller action after you've handled the form.
$this->redirect($this->get('router')
->generate('mypath',
array('myparam'=>
$this->getRequest()->get('myparam')
),
true);
My question may sound naive, but really struggling to do a very simple thing. Suppose I have to html page - send.html and receive.html.
In send.html page -
I have text field and a button in like following -
<body>
<form onsubmit="recieve.html">
<input type="text" id="mytextfield">
<input type="submit" id="submitbutton" value="Go">
</form>
</body>
Here I want to put something on the textfield and I want to see that value in the receive page some thing like - Hello 'value of textfield'. That's it.
Do I need to use JS cookie for that? If not, how can I do it in the most simple way?
Need help :(
The most simple way is PHP. Bottom line is you need something handling the data on the server side.
With javascript you can write a function to store the value in a cookie and read it on the next page. By the way, your page goes in the action attribute. onsubmit expects a javascript function, not a page.
