I've searched in vain for days, but haven't found a solution for my problem yet.
Ideally, I would like to embed a fillable pdf form into an intranet html form for submission to the server for processing (ability to parse the field/values would be gravy, but not required). The files are all in the same domain so no cross-domain issues. I know I could add submission functionality to the pdf form itself, but 1) scripting is beyond the ability of the pdf document administrator and I don't want to take that on, 2) there are hundreds of pdf documents, 3) I need additional scripted fields/values submitted with the form, 4) I want the pdf document to be contained within the login session. So far, the server log shows all the field/values, except the PDFInput parameter which is passed, but the value is empty.
Here's what I have so far:
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<script>
$(document).ready(function() {
$(uploadForm).on("submit", function(event) {
var iframe = document.getElementById('PDFObj');
var iframeDocument = [iframe.contentDocument || iframe.contentWindow.document];
var pluginData = iframeDocument;
$(this).append('<input type="file" name="PDFInput" id="PDFInput" value="' + pluginData + '" style="visibility:hidden"/>');
return true;
});
});
</script>
and
<form enctype="multipart/form-data" method="post" name='uploadForm' id='uploadForm'>
<input type='hidden' name='rm' id='rm' value='uploadFile'>
<table align='center'>
<tr>
<td align='left'>
<strong>Notes:</strong>
<br>
<textarea cols='80' rows='2' name='notes' id='notes'></textarea>
<br>
<br>
</td>
</tr>
<tr>
<td colspan=2 align='center'>
<input type='submit'>
</td>
</tr>
<tr>
<td colspan=2>
<br>
<input type='hidden' name='formid' id='formid' value='6F45B3AF-91F3-108C-D3D9-701F541B49DC'>
<iframe type='application/pdf' src="url.pl?formid=6F45B3AF-91F3-108C-D3D9-701F541B49DC.pdf" height='800' width='1000' name='PDFObj' id='PDFObj'>
</td>
</tr>
</table>
</form>
I've tried embedding it using iframe and object along with setting input type="object", but I can't get any combination to work.
Is this even possible? Is there a better approach?
As far as I know, you're not going to be able to capture the PDF data directly from HTML like that. Your best bet is going to be to add submit functionality to the PDFs, then process the resulting FDF data with a server-side script.
You will need either add Submit a Form buttons to your PDFs, or modify the existing buttons. Make sure the form action in the PDF has #FDF after the URI (eg https://example.com/process.php#FDF).
Parsing the data server side is simple. I'm not sure what server side language you are using, but here is a PHP snippet
<?php // process.php, report the data we received
echo '<h2>GET Data</h2>';
foreach( $_GET as $key => $value ) {
echo '<p>Key: '.$key.', Value: '.$value.'</p>';
}
echo '<h2>POST Data</h2>';
foreach( $_POST as $key => $value ) {
echo '<p>Key: '.$key.', Value: '.$value.'</p>';
}
Note that a PDF only interacts with a web server properly when viewed inside of a web browser.
I do not know of a reliable way to programmatically add submit buttons to PDFs, nor do I know of a reliable conversion method. You're between a rock and a hard place here IMHO.

I've got this research.php file that should show the content of a database table, taking the informations for the query from a javascript form.
I made in javascript the form and disabled the enter key, so that only by hitting the button you can submit the value. The value of the components in the form should be used to make the query. Can I pass the value to a php variable in the same file?

In this code the button click just call the interact function, that show an alert window with the value of the variables.
I tried to use ajax but, as far as I understood, it would open a new file.
I've also seen a solved answer in which someone suggested to use the cookies, but that solution really disgusted me.
The most helpful thing I found is here:
How do i store select value into a php variable,
but the POST method refresh the page and the slider crushes.
If you want to pass a variable from JS to PHP you are going to want to use AJAX, it allows you to send and receive info from server running the PHP script.
Your Javascript:
var infobeingsent = "test";
$.ajax({
type: "POST",
url: 'YOURPHPFILE.php',
data: { testVAR : infobeingsent },
success: function(data)
{
alert("data has been sent");
var recievedvar = data;
}
});
Your php file:
if(isset($_POST['testVAR']))
{
$recievedvar = $_POST['testVAR'];
echo "Hey, ive recieved your request";
}
Using AJAX means that your browser never has to come into direct contact with the php file and there's no interruption from the end-users perspective
I think you are a bit confused about the whole work flow between php (server side) and js (client side). OR may be I got your question wrong. But here is a hint on how you can approach this.
You have a server side running php - Great.
You have an html page with js - Awesome.
In the html page, you have a form that you want to run a query based on the user submission:
AJAX is the way. You can do it with pure javascript or a plugin like jquery. On the php side, you can even keep a small, seperate script just to handle this request, run the query and generate the result. Use "onSubmit" for the form to invoke ajax.
I'm making an application to import excel to database using excel_reader2.php. I created a form for uploading excel file and when the file that I want to upload selected, I want to read data boundsheet of the excel file. which become problems when I using js, I could not parsing the $ _FILES in php code.
<script type="text/javascript">
function sheetChange()
{
var html;
$("#sheetName td").remove();
var fileInputContent = $('#form').serializeArray();
$.post(basedomain+"mycontroller/readSheet",fileInputContent,function(result)
{
if(result)
{
$("#sheetName").show();
var data = JSON.parse(result);
html += '<td>Sheet Name</td><td colspan=\'3\'><select name=\'SHEET\' required>';
for(var i in data)
{
html += '<option value=\''+data[i]+'\'>'+data[i]+'</option>';
}
html +='</select></td>';
$("#sheetName").append(html);
}
});
}

<tr>

{
error_reporting(E_ALL ^ E_NOTICE);
require_once 'excel_reader2.php';
$data = new Spreadsheet_Excel_Reader($_FILES['file']['tmp_name']); //$_FILES is null
foreach ($data->boundsheets as $k=>$sheet)
{
$row[] = $sheet['name'];
}
echo json_encode($row);
exit;
}
anyone can help me?Thanks in advance.
the reason is that uploading files using HTML is not as simple as you might think. Here are two nice examples how a normal POST looks like (in the HTTP Protocol) versus how a multipart/form-data request looks like:
http://www.htmlcodetutorial.com/forms/form_enctype.html
The thing to take away from here is, that form submits and form submits with file upload are technically two very different things.
$.post can only do the normal form submit for you, file uploads are not supported by jQuery.
There are two ways you can get around this:
just do a plain form submit (the simpler approach)
you'll have to programmatically add the file to the request. If you go for this option, there's a plugin you might use (never tried it though): https://github.com/blueimp/jQuery-File-Upload/wiki/How-to-submit-additional-form-data

The forums have been a huge help on this project so far. I'm looking for some guidance on the next step of my project here.
What I have is a form that feeds user submitted information into a MySQL database. This database then feeds this information to a main page displaying all of the information in the DB. What I am looking to do is add something to my form that creates a new unique URL/page when the form is submitted. I have already designed the HTML/CSS template for this page and it is designed to display only one set of information as opposed to the entire DB worth.
I am looking for some guidance as to how I can create the pages and unique URLs on the form submit. What is the best way to get this fresh information feeding from the DB immediately?
I need to somehow automatically recreate the HTML and CSS files as well on the server, this I am unfamiliar with.
EDIT: After #Jacky Cheng pointed out that this was possible without creating new versions of the HTML/CSS files I would be inclined to go about having a single HTML file on the server that is dynamic.
Thanks for any help as you guys have been great so far.
Including code for the form which I am submitting to the DB from, and the page which I will be pulling info from.
This is the form:
<?php
include_once 'post_func.inc.php';
connect();
?>
<!DOCTYPE html>
<html>
<head>
<title>Event Register</title>
</head>
<body>
<div style="text-align: center">
<h2>Event Register</h2>
<form id="eventregister"action="eventtestconnect.php" method="post">
<table style="border: 0; margin-left: auto; margin-right: auto; text-align: left">
<tr>
<td>Event Name:</td>
<td><input name="name" type="text"></td>
</tr>
<tr>
<td>Event Type:</td>
<td>
<select name="eventtype">
<?php query_eventtype() ?>
</select>
</td>
</tr>
<tr>
<tr>
<td>Venue:</td>
<td>
<select name="venue">
<?php query_venue() ?>
</select>
</td>
</tr>
</table>
<input type="submit" value="Submit">
</form>
</div>
</body>
<?php close() ?>
</html>
This is the page I want filling with information from the DB after the form is submitted and the url is generated.
<?php
include_once 'event_func.inc.php';
connect();
?>
<html>
<head>
<title>
<?php query_eventname() ?>
</title>
<link href="eventstest.css" rel="stylesheet" type="text/css"/>
</head>
<body id="body">
<div id="maincontainer">
<div id="header">
</div>
<div id="content">
<div id="eventname">
<?php query_eventname() ?>
</div>
<div id="eventvenue">
<?php query_eventvenue() ?>
</div>
<div id="eventicon">
<?php query_eventtype() ?>
</div>
</div>
</div>
</body>
<?php close() ?>
</html>
What changes need to be made to the form in order for the url to be generated on submit and the event page to be able to jump between urls/sets of data dynamically, per-say?
Sorry for the beginner questions but this site really seems to be the best resource for these sorts of things and I haven't found anything this specific on here!
Thanks again for the help!
I am still half guessing what you want, so bear with me here.
from the description of your question, you seems to have a system that would generate an actual html file per form submit? That doesn't look good to me.
maybe try something like this :
redesign a web page that would take http GET request parameter as input (mydomain.com/display.php?id={input1}) and display only 1 set of info.
from the comments I see you have a unique id per form submit, I'd suggest avoid using it directly in the request as it'll be extremly easy to get someone else's info. Instead try somthing like MD5 encoding for that id and then sending that out to user.
so the overall system would be:
1) you'll only ever have 1 html file in your server, which will dynamically change it's content according to input, which save you a lot of space.
2) you'll have a unique & slightly more secure URL per form submit
edit:
here are some fake code to show the general idea.
form response:
$uniqueId=mysql_query("SELECT unique_id FROM my_db");
echo "http://yourdomain.com/display.php?urlid=".$uniqueId;
display.php
<?php
$uniqueId=$_GET['urlid'];
mysql_query("SELECT info_you_need FROM your_tables WHERE unique_id = $uniqueId");
?>
<html><body>your display page html here</body></html>
I guess...
You want to create product catalog page like this:
www.abc.com/Electronics/Product-Motorola-moto-g-at-Rs6999-only.html
and this will display all the product information from the database.
If the above is your case then you can use url rewrite in your project.
RewriteEngine On # Turn on the rewriting engine
RewriteRule ^Product-/?$ Product-Motorola-moto-g-at-Rs6999-only.html [NC,L] # Handle requests for "Product-"
The "RewriteRule" line is where the magic happens. The line can be broken down into 5 parts:
RewriteRule - Tells Apache that this like refers to a single RewriteRule.
^/Product/?$ - The "pattern". The server will check the URL of every request to the site to see if this pattern matches. If it does, then Apache will swap the URL of the request for the "substitution" section that follows.
Product-Motorola-moto-g-at-Rs6999-only.html - The "substitution". If the pattern above matches the request, Apache uses this URL instead of the requested URL.
[NC,L] - "Flags", that tell Apache how to apply the rule. In this case, we're using two flags. "NC", tells Apache that this rule should be case-insensitive, and "L" tells Apache not to process any more rules if this one is used.
Handle requests for "Product" - Comment explaining what the rule does (optional but recommended)
Hope this will work for you.
Feel free to ask any help.
Happy programming :)
Bear with me too. Your description is pretty bad. So if I am correct, you want form=>mysql=>confirmation
So, form should be action="process.php" method="post"
Create a process.php file where you do your validation, escaping, serializing, etc. Insert into the MySQL table. If returns true redirect (header(location:yourdomain.com)) and then on the redirected page, select the information from the Database.
Hello I have an option list in html that is created dynamically by php. I want to take the value of the option list withought subbmiting everything and then call another php function to fill another option list. To be more specific I want the user to first pick a University from a database and then to pick a department of that Universe. I 've created dynamicaly the option list for the Uni's by fetching all Uni's from the database and then find the value by javascript. So in the javascript function I want to write php code in order to fetch all the departments from the university. Eveything works fine until I try to call the php function from the javascript.

return;
var value=document.getElementById('selection').value;
alert(value);
document.getElementById('dep').innerHTML=" <?php include './selectDep.php'; selectDep("+value+"); ?> ";
return true;
}
the value at the alert is correct
selectDep.php
<?php
//just trying to make this work for now
function selectDep($value){
echo $value;
}

I cannot understand what I am doing wrong. Everything look fine to me. Can you help me?
First You have to understand that the javascript code executes in web browser but the php code executes in web server.
You can use AJAX to fix your problem.
PHP is a server-side scripting language. It is executed on the server, which means the page has to submit values to the server as a trigger. Javascript and HTML are client-side, which means it's all done in the browser without communicating with the server.
To see this in action, right-click on a PHP page in the browser and select to view source. All you will see is the HTML, you will not be able to view any of the PHP code that generates the page. When PHP executes on the server, the result is client-side code (javascript, HTML and maybe CSS) which is sent to the browser.
The browser wouldn't know what to do with PHP code. If you set the inner HTML of an element to some PHP code in client-side script, it won't get executed and all you will achieve is having the browser render the PHP script exactly as you entered it.
In short, the javascript has to submit the selected value back to the server, before the server-side PHP can work out which departments to send back to the browser.
I trying to store CSV data to database using onclick function. Unfortunately, I am using php code inside javascript function which is not efficient enough. Therefore, I hope that I can get any suggest or solution to improve efficiency of my project by using javascript instead of php to store CSV data into database.
This is javascript with php code :
<script>
function storeQueEmail(){
<?php
$file = $_FILES[csv][tmp_name];
$handle = fopen($file,"r");
//loop through the csv file and insert into database
do {
if ($data[0]) {
$record['contact_first'] = $data[0];
$record['contact_last'] = $data[1];
$record['contact_email'] = $data[2];
$record['subject'] = $_REQUEST['subject'];
$record['message'] = $_REQUEST['message'];
$record['status'] = 0;
$oAdminEmail->insertQueEmail($record);
}
} while ($data = fgetcsv($handle,1000,",","'"));
?>
}
</script>
This is HTML code :
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Import a CSV File with PHP & MySQL</title>
</head>
<body>
<form action="" method="post" enctype="multipart/form-data" name="form1" id="form1" >
Subject : <br/>
<input type="text" name="subject" id="subject" required/> <br/>
Choose your upload type: <br />
<input name="csv" type="file" id="csv" accept=".csv" required/> <br/>
Content : <br/>
<textarea name="message" cols="50" rows="10" required></textarea><br/>
<input type="submit" name="submit" value="Submit" onclick="storeQueEmail()"/>
</form>
</body>
</html>
what are you trying to do there? I think you are speaking about a PHP in
HTML document. So your PHP code inside your function is interpreted on server. As your PHP code has no output your Javascript function is simply empty. Thus as you have registered your Javascript function as onclick handler just nothing would happen.
Remember that standard Javascript code is interpreted on Client (that means in browser) though you PHP code is interpreted on server. As mentioned in the comments above it is possible to use an AJAX or POST/GET - Request to send data to your server and then write it to your DB or file etc.
Another way to do this directly with Javascript is Node.js - serverside Javascript that is able to write to your Database like PHP can do.
The easiest way for you to do it with your HTML code you presented above is to fill in your
action - attribute
in your
form tag
For example:
<form action="proccessData.php" ...>
...
</form>
Don't forget to remove your onclick - attribute inside form's submit input field.
If you know press your submit button your entire form and its content will be send to http://www.xyz.de/proccessData.php. Inside that file you can work with your form data: In your case two text fields and one file upload field. As you may know you could get to the content of text input field send via post via:
$_POST['<name of field>']
To get your uploaded file and proccess it you could use PHP's global
$_FILE[] - Array
Just refer to PHP's manual on php.net or some other online documentation. There's pretty much to find on the web.
I just give you a helpful link to php.net on how to handle file uploads in a correct and therefor secure manner: http://us2.php.net/manual/en/features.file-upload.php
Once you have read your uploaded file via PHP's global $_FILE[] - array just proccess that file via fgetcsv in your proccessData.php and write it line for line to your database.
Hope that helps! It is really not that hard :)
