i want to get value of input of my form via $_post in my insert page but my problem is that i get error massage:undefined index:track_code and i cant get value of it.the names is same what is problem?
this is my problem why stackoverflow want more detail. this is all detail
<form action="insert.php" method="post">
<input name="track_code" type="text" class="tiny-size" value="<?php echo $track_code_rnd ; ?>" style="width: auto;height: auto" disabled />
</form>
<form action="insert.php" method="post" class="form-horizontal form-checkout">
<div class="control-group">
<label class="control-label" for="firstName">نام<span class="red-clr bold">*</span></label>
<div class="controls">
<input name="first_name" type="text" id="firstName" class="span4" >
</div>
</div>
<div class="control-group">
<label class="control-label" for="lastName">نام خانوادگی<span class="red-clr bold">*</span></label>
<div class="controls">
<input name="last_name" type="text" id="lastName" class="span4">
</div>
</div>
<input name="submit" type="submit" class="btn btn-success" value="خرید" style="width: 66px"/>
</form>
<form action="insert.php" method="post">
<input name="track_code" type="text" class="tiny-size" value="<?php echo $track_code_rnd ; ?>" style="width: auto;height: auto" disabled />
</form>
<?php
$track_code = $_POST['track_code'];
?>
Set this one code in your form
<form action="insert.php" method="post">
<input name="track_code" type="text" class="tiny-size" value="<?php echo ($track_code_rnd)?$track_code_rnd:'';?>" style="width: auto;height: auto" disabled />
</form>
Remove disable tag from your input code. Disable controls wont be posted on server. for that you can make it readonly or make it hide
Try Putting the PHP code on the form. as given below.
<?php
if (isset($_POST['submit'])) {
$track_code = $_POST['track_code'];
}
?>
<form action="your_page.php" method="post">
<input name="track_code" type="text" class="tiny-size" value="<?php echo $track_code_rnd; ?>" style="width: auto;height: auto" readonly />
<input name="submit" type="submit" />
</form>
It will execute the whole file as PHP. The first time you open it, $_POST['submit'] won't be set because the form has not been sent. Once you click on the submit button, it will print the information.
Disabled controls never post on server. So make it readonly or hidden.

I am having issues with a piece of code in Joomla. It may be something to do with the plugin that enables the PHP but in case it isn't.
Page 1 has a form
<form action="/index.php/bridge" method="POST" name="postcode">
<div><input style="height: 50px;" type="text" placeholder="Enter Your Postcode..." /> <input type="submit" value="Get Started today!" /></div></form>
The text you input becomes the variable I want to pass over
On Page 2
<?php echo "test";
$postcode=1;
$poster=$_POST['postcode'];
echo $poster;
// You can place PHP like this
?>
Unfortunately, the postcode isn't echoed
Assuming nothing else is the cause of this error, try naming the input you are sending over to postcode:
<form action="/index.php/bridge" method="POST">
<div>
<input style="height: 50px;" name="postcode" type="text" "placeholder="Enter Your Postcode..." />
<input type="submit" value="Get Started today!" />
</div>
</form>
In your PHP code you are echoing $_POST['postcode'] but you are not sending the same variable at the time of form submission from input attribute.
<form action="/index.php/bridge" method="POST" name="demoForm">
<div>
<input style="height: 50px;" name="postcode" type="text" "placeholder="Enter Your Postcode..." />
<input type="submit" value="Get Started today!" />
</div>
</form>
Try this
<form action="/index.php/bridge" method="POST">
<div>
<input name="postcode" style="height: 50px;" type="text" placeholder="Enter Your Postcode..." />
<input type="submit" name="submit" value="Get Started today!" />
</div>
<?php
if (isset($_POST['submit'])){
echo $poster = $_POST['postcode'];
}else{
echo $poster = 1;
}
?>
Can i add variables to an HTML page ?
Example:
I have this:
<form action="[FORUM_LOGIN_URL/]" enctype="application/x-www-form-urlencoded" id="loginForm" method="post" name="loginForm" onsubmit="return handleLogin();">
<div id="loginFormContainer">
<input id="loginField" name="login" type="hidden" value="login">
<input id="redirectField" name="redirect" type="hidden" value="[REDIRECT_URL/]">
<div>
<label for="userNameField">[LANG]userName[/LANG]:</label><br>
<input id="userNameField" maxlength="[USER_NAME_MAX_LENGTH/]" name="username" readonly="readonly" type="text" value="Liel">
</div>
<div>
<label for="passwordField">אין צורך בסיסמה:</label><br>
<input id="passwordField" name="password" readonly="readonly" type="password">
</div>
<div>
<label for="languageSelection">[LANG]language[/LANG]:</label><br>
<select id="languageSelection" name="lang" onchange="ajaxChat.switchLanguage(this.value);">
</select>
</div>
<div>
<input id="loginButton" name="submit" type="submit" value="[LANG]login[/LANG]">
</div>
</div>
</form>
I need a variable in the value:
<input type="text" readonly="readonly" value="!variable!" name="username" id="userNameField" maxlength="[USER_NAME_MAX_LENGTH/]"/></div>
I have also the lang.php and if i can add variable in lang line:
$lang['langexample'] = 'variable';
You can simply add php code in html with php tag. For example
<?php echo $something; ?>
Before that you need to make sure, you file have to save as ".php" extension.
Im having issues with a ''profile'' page where users will be able to change their username, email, name, password and so on but it seems to have conflicts when i have more than 1 form on the page as they all work individually?
I could be missing something obvious so if anyone could help id much appreciate it.

Hello You haven't mentioned what problem you actualy facing but this seems like the problem is the unique identification of a form at server side
Please see this post
Multiple HTML Forms on One Page
Hope this will help ;)
Have each form action set to the current page, and use hidden inputs to determine what action is being taken. Using this method will prevent the user from being dropped onto a different page, and puts the action being taken into a variable that you can use or manipulate.
If you want to have separate PHP scripts for actual functions, use includes or requires.
<form action="" method="post">
<div class="field">
<label for="username">Username:</label>
<input type="text" name="username" id="username" value="<?php echo escape($user->data()->username); ?>">
<input type="submit" value="Update">
<input type="hidden" name="token" value="<?php echo Token::generate(); ?>">
<input type="hidden" name="action" value="changeUsername">
</div>
</form>
Then the PHP script gets the action from the POST and uses a switch to determine which functions to call.
if (isset($_REQUEST['action'])) {
$action = $_REQUEST['action'];
switch ($action) {
case "changeUsername":
changeUsername();
break;
case "changePassword":
...
As mentioned, if you want to have these functions in separate php files, you can use include or require.
This conveniently drops the user right back on the same page when they update information, so that they can make additional updates.
How do I make this code (custom):
<div id="sb-search" class="sb-search">
<form>
<input class="sb-search-input" placeholder="Search.." type="text" value="" name="search" id="search">
<input class="sb-search-submit" type="submit" value="">
<span class="sb-icon-search"></span>
</form>
</div>
retrieve search results like this one ( wordpress ) does:
<form method="get" class="searchform" action="<?php echo home_url('/'); ?>">
<div>
<input type="text" class="search" name="s" onblur="if(this.value=='')this.value='<?php _e('To search type and hit enter','typegrid'); ?>';" onfocus="if(this.value=='<?php _e('To search type and hit enter','typegrid'); ?>')this.value='';" value="<?php _e('To search type and hit enter','typegrid'); ?>" />
</div>
Basically I got this custom code for an awesome search box with on-click slide etc. It has a field where people can type, but it gets no results as used on my wordpress site. I wanna make it able to get results from wordpress content w/o changing divs thus not altering its design. Please help, I'm stuck!!
This would do it:
<div id="sb-search" class="sb-search">
<form action="<?php echo home_url('/'); ?>">
<input class="sb-search-input" placeholder="Search.." type="text" value="" name="s" id="search">
<input class="sb-search-submit" type="submit" value="">
<span class="sb-icon-search"></span>
</form>
</div>
All you have to do is add the form action, and make the name of the search input to be "s".
<form method="get" class="searchform" action="<?php echo home_url('/'); ?>" >
<input class="sb-search-input" placeholder="Search.." type="text" value="" name="s" id="search">
<input class="sb-search-submit" type="submit" value="">
<span class="sb-icon-search"></span>
</form>
homeurl ?s=anything will call wordpress search function, so just make form's action GET and ACTION = your home url
I would like to know how do I edit in HTML5 validation message if there is error in form.
<form method="post" id="login" action="<?php echo $_SERVER['PHP_SELF']?>">
<div class="form_settings">
<label for="textfield">Meno:</label>
<input class="zaoblene" type="text" name="meno" value="Meno....." onclick="javascript: document.forms['login'].meno.value=''" required>
<br><br>
<label for="textfield">Heslo:</label>
<input class="zaoblene" type="password" name="heslo" value="heslo....." onclick="javascript: document.forms['login'].heslo.value=''" required>
<br><br>
<input class="prihlasit" type="submit" name="prihlasit" value="prihlásit" >
</div>
</form>
You can use javascript to do it!
Here you've the jquery plugin that does this work : http://bassistance.de/jquery-plugins/jquery-plugin-validation/
