When I click on "Comment", it is not opening the new file $cname.txt hence not able to insert values in file and therefore nothing is posted. I want that cname and comment to be posted when the user clicks submit? Here is my code:
<?php
$name="";
/*print_r($_POST);*/
if(isset($_POST['submit'])) {
global $name;
$name=$_POST['name'];
$query=$_POST['query'];
$my_query="My query";
/* $files=fopen("$name.txt","w");
fclose($files); */
$po="$name <br> $my_query:$query \n";
$myfile=fopen("posts.txt","a+");
fwrite($myfile,$po);
fclose($myfile);
}
$mypost=fopen("posts.txt","r");
while($line = fgets($mypost)) {
echo '<form class="w3-container w3-card-4 w3-light-grey w3-text-blue w3-margin">
<div class="w3-row w3-section">
<div class="w3-col" style="width:50px"><i class="fa fa-question-circle-o" style="font-size:30px"></i></div>
<div class="w3-rest">
<p class="w3-input w3-border"><i class="fa fa-user-circle-o"></i>'.$line; echo '</p>
</div>

<form method="post" action="' .htmlspecialchars($_SERVER['PHP_SELF']); echo '">

' ; }
$cname="";
if(isset($_POST['submits'])) {
global $cname;
$cname=$_POST['cname'];
$comment=$_POST['comment'];

You can do it like this for your field.
I want to validate if the textbox has a value or not. Right now what I have is a textbox that has a value but the output says it is empty here is it it is like nothing is being conditioned on the code please see me code, thank you
Full Code
-Here is the full code of my form please take a look thank you very much
<form>
<div class="row">
<form method="POST">

$code = 'Code';
$code2 = 'PIN';
if(isset($_POST['btnSubcode'])) {
$lblCode = isset($_POST['lblQrTxt']) ? $_POST['lblQrTxt'] : '';
$code = $lblCode;
$code = explode(":",$code); // code = array("QR Code","444444444|123")
$code = explode("|",$code[1]); // code[1] = "444444444|123"
$code = trim($code[0]); // 444444444
$code2 = $lblCode;
$code2 = explode(":",$code2); // code = array("QR Code","444444444|123")
$code2 = explode("|",$code2[1]); // code[1] = "444444444|123"

my textbox

You might be over complicating it. It is pretty simple.
<?php
if(isset($_POST['txt']) && $_POST['txt'] != '') {
echo "Text Present";
} else {
echo "Text Not Present";
}
?>
Additionally I would recommend you filter all input on post or get. Basically anything that gets information from a user.
Check here - http://php.net/manual/en/function.filter-input.php
<?php
$my_txt = filter_input(INPUT_POST, 'txt');
if(isset($my_txt) && $my_txt != '') {
echo "Text Present";
} else {
echo "Text Not Present";
}
?>
Also you need to add a submit button between your form tags. Like this.
<input type="submit" value="Submit">
Also you should have only one closing tag for every opening tag. This is called valid HTML.
For example a valid form is like
<form method="post">
First name:<br>
<input type="text" name="firstname" value="Mickey"><br>
Last name:<br>
<input type="text" name="lastname" value="Mouse"><br><br>
<input type="submit" value="Submit">
</form>
Ok I have made a simple php test file and tested it works. Your problem is:
You don't have a submit button. The $_POST will not be there if you do not submit a form first.
It would be easier to validate your textarea using javascript instead.
Here is my test file and it works:
<html>
<body>
<form method="POST">
<textarea name="txtQrtxt">
</textarea>
<input type="submit">
</form>
<?php
$var = $_POST['txtQrtxt'];
if (strlen($var)<=0) {
echo "Textarea empty";
} else {
echo "Textarea Okay";
}
?>
</body></html>
i have a problem with a form in codeigniter. i have tried different things but i can not find a solution.
this is the form:
<form method="post" action="<?php echo base_url(); ?>cms/cms/newUser">
<div class="row">
<div class="col-md-3">
Naam:
</div>
<div class="col-md-9">
<input type="text" id="naam" name="username" />
</div>
</div>
<div class="row">
<div class="col-md-3">
E-mail:
</div>
<div class="col-md-9">
<input type="email" name="mail" id="email" />
</div>
</div>
<div class="row">
<div class="col-md-3">
Passwoord:
</div>
<div class="col-md-9">
<input type="password" name="pass" id="password" />
</div>
</div>
<div class="row">
<div class="col-md-8 col-md-offset-2">
<input type="submit" name="aanmaken" class="btn btn-block btn-info" value="aanmaken" />
</div>
</div>
in my controller i process the data coming from the form.
the controller is located at controllers/cms/cms.php
class Cms extends MY_Controller
{
public function newUser()
{
if(isset($_POST))
{
echo "verwerk deze data <br>";
if(isset($_POST['username']))
{
echo 'naam is set!';
}
else {
echo 'naam is not set!';
}
$naam = $_POST['username'];
$mail = $_POST['email'];
$pass = $_POST['password'];
echo "naam: " . $naam . "<br>";
echo "mail: " . $mail . "<br>";
echo "pass: " . $pass . "<br>";
$time = new DateTime();
$time->setTimezone(new DateTimeZone ('Europe/Brussels'));
$tijd = $time->format('Y-m-d H:i:s');
include_once('application/libraries/PasswordHash.php');
$hasher = new PasswordHash(12,false);
$passwoord = $hasher->HashPassword($pass);
$gebruiker = new Gebruiker();
$gebruiker->naam = $naam;
$gebruiker->email = $mail;
$gebruiker->paswoord = $passwoord;
$gebruiker->laatsteLogin = $tijd;
$gebruiker->active = 0;
echo "coded pas" . $passwoord . "<br>";
}
else
{
echo "no post";
}
}
when i check my website and fill in the form i get 3 php error that the values that i put in the variable from the post does not exist. also the if(isset) function says that the variable is not set. i don't know why the form action doesn't work.
i even tried the codeigniter way but it gave the same result.
$name = $this->input->post('username');
thanks for the help.
HTML:
enter code here
<form method="post" action="<?php echo site_url(); ?>/cms/cms/newUser">
<div class="row">
<div class="col-md-3">
Naam:
</div>
<div class="col-md-9">
<input type="text" id="naam" name="username" />
</div>
E-mail:
<div class="row">
<div class="col-md-3">
Passwoord:
</div>
<div class="col-md-9">
<input type="password" name="pass" id="password" />
</div>
</div>
<div class="row">
<div class="col-md-8 col-md-offset-2">
<input type="submit" name="aanmaken" class="btn btn-block btn-info" value="aanmaken" />
</div>
</div>
PHP:
class Cms extends MY_Controller
{
public function newUser()
{
if(isset($_POST))
{
echo "verwerk deze data <br>";
if($this->input->post('username'))
{
echo 'naam is set!';
}
else {
echo 'naam is not set!';
}
$naam = $this->input->post('username');
$mail = $this->input->post('mail');
$pass = $this->input->post('pass');
echo "naam: " . $naam . "<br>";
echo "mail: " . $mail . "<br>";
echo "pass: " . $pass . "<br>";
$time = new DateTime();
$time->setTimezone(new DateTimeZone ('Europe/Brussels'));
$tijd = $time->format('Y-m-d H:i:s');
include_once('application/libraries/PasswordHash.php');
$hasher = new PasswordHash(12,false);
$passwoord = $hasher->HashPassword($pass);
$gebruiker = new Gebruiker();
$gebruiker->naam = $naam;
$gebruiker->email = $mail;
$gebruiker->paswoord = $passwoord;
$gebruiker->laatsteLogin = $tijd;
$gebruiker->active = 0;
echo "coded pas" . $passwoord . "<br>";
}
else
{
echo "no post";
}
}
$this->input->post('') will check automatically not need of isset().
$this->input->post('') will take name not id
In the form tag
<form method="post" action="<?php echo base_url(); ?>cms/cms/newUser">
cms is the name of the controller and you have used it twice. Try with
<form method="post" action="<?php echo base_url(); ?>cms/newUser">
you need to pass only controllername/func_name and keep your controller file in controller dir
then try in CI way
<?php echo form_open("cms/newUser");?>
<?php echo form_close();?>
or
<form method="post" action="<?php echo base_url(); ?>cms/newUser">
Else you need to use routing for this and tell to pick this controller on that route
for this go to config/routes.php and add route like:-
$route['cms'] = "cms/cms";
try to load form helper and use this code
controller:
$this->viewContent['form_action'] = base_url()."cms/cms/newUser";
$this->load->view('your_view_page',$this->viewContent);
view:
echo form_open($form_action);
I have following code:
<html>
<head>
<meta charset="UTF-8"/>
</head>
<body>
<!--See siin all tekstiväli-->
<H3>Minu küsitlused </H3>
<hr>
<br>
<br>
<br>
<ol>
<?php
include_once 'init/init.funcs.php';
$result = mysql_query('SELECT * from katse_kysimustik_pealkiri');
while($row = mysql_fetch_assoc($result)) {
$titles[] = $row['pealkiri'];
}
foreach($titles as $title) {?>
<li>
<?php echo $title ?>
<form action='Minu_kysitlused_1.php' method="post">
<input type="submit" name = "saada" value="saada"/>
<input type="button" value="tulemused"/>
<input type="button" value="lõpeta ennetähtaegselt"/>
<input type="button" value="X"/>
</li>
</form>
<?php
}
?>
</ol>
</body>
</html>
<?php
if(isset($_POST['saada'])){
header("Location:http://localhost/Praks/saada.html");
}
?>
Right now there is button "saada" for each title in database. When I click "saada", page saada.html will appear.
This is saada.html
<!doctype html>
<html>
<head>
<meta charset="UTF-8"/>
<title>Saada</title>
</head>
<form action="test1.php" method="POST">
<body>
<header>Küsitluse pealkiri</header>
<br>
Lisa sõnumile pealkiri:
<br>
<textarea rows='1' name='pealkiri'>Küsitluse algne pealkiri</textarea>
<br>
Lisa Adressaadid: <br>
<textarea rows='1' name='email'></textarea>
<br>
Lisa sõnum:
<br>
<textarea rows='4' name='tekst'></textarea>
<br><footer>
<INPUT TYPE="submit" VALUE="Saada" NAME="Saada">
</form>
<FORM METHOD="LINK" ACTION="Minu_kysitlused.html">
<INPUT TYPE="submit" VALUE="Loobu">
</footer>
</body>
</html>
My question is how could I make it work so value of $title appears in saada.html. The value of this $title which is next to 'saada' button I clicked. I need this value to be in this line instead of Küsitluse algne pealkiri:
<textarea rows='1' name='pealkiri'>Küsitluse algne pealkiri</textarea>
You can not have a value through PHP in HTML type page....change page extension to .php
then pass your $title in input hidden field in your form
like this
foreach($titles as $title) {?>
<li>
<?php echo $title ?>
<form action='Minu_kysitlused_1.php' method="post">
<input type="submit" name = "saada" value="saada"/>
<input type="button" value="tulemused"/>
<input type="button" value="lõpeta ennetähtaegselt"/>
<input type="button" value="X"/>
<input type="hidden" name="title" value="<?php echo $title;?>"/>
</li>
</form>
<?php
}
?>
Now set the cookie
<?php
if(isset($_POST['saada']))
{
if(isset($_REQUEST['title']))
{
$title = $_REQUEST['title'];
setcookie("page_title", $title, time()+3600);
}
header("Location:http://localhost/Praks/saada.html");
}
?>
Now on Your saada.html you can use js to retrieve cookie like this
JS Function Reference
var title = getCookie("page_title"); // retrieve cookie
document.getElementById('page_title').value = title; // put title into textaread
function getCookie(name) {
var value = "; " + document.cookie;
var parts = value.split("; " + name + "=");
if (parts.length == 2) return parts.pop().split(";").shift();
}
<textarea rows='1' name='pealkiri' id="page_title" >Küsitluse algne pealkiri</textarea>
I am writing an app to delete and modify files in a directory. I deleted files successfully. And now I want to modify and update content to the same file using textarea on another page.
<form enctype="multipart/form-data" method="post">
<div class="span7">
<table>
<thead>
<tr>
<th> List of files </th>
<tr>
</thead>
<?php
$files = glob("UploadFile/"."*");
foreach($files as $txt)
{
if(mime_content_type($txt)=="text/plain")
{
$txtname = basename($txt);
echo "<tr><td><input type='radio' name='txt' value='$txtname'/> ".$txtname."</td></tr>";
}
}
?>
</table>
</div>
<div class="span8">
<button type="submit" name="submit" value="Edit">Edit</button>
<button type="submit" name="submit" value="Delete">Delete</button>
</div>
<?php
global $txtname;
$val = $_POST["submit"];
$txtname = $_POST["txt"];
if($val=="Delete")
unlink("UploadFile/".$txtname);
else if($val=="Edit")
{
$content=file_get_contents("UploadFile/".$txtname);
header('Location:/edit.php');
/* send content to this 'edit.php' page */
}
?>
</form>
And the edit.php page, i simply checked if the code is working. It works fine.
<?php
if($_POST['append'])
{
$file_open = fopen("UploadFile/file.txt","a+");
fwrite($file_open, $_POST['append']);
fclose($file_open);
}
?>
<form enctype="multipart/form-data" action="<?=$PHP_SELF?>" method="post">
<textarea name="append" value="">
<?php
echo $content;
$datalines = file ("UploadFile/file.txt");
foreach ($datalines as $zz)
{
echo $zz;
}
?>
</textarea>
<button type="submit" name="submit" value="save"> Save </button>
How do I get the contents of the file to textarea for modifying it.Update: I want to save changes to the same file. Thank you
<?php
if(isset($_POST['text']))
{
file_put_contents("file.txt",$_POST['text']);
