I'm trying to cache the user input in my form. My code is:
echo '
<form method="POST">
Name:<br /><input class="contact_name" type="text" name="contact_name" maxlength="32" placeholder="Enter Name" /><br />
Email:<br /><input class="contact_email" type="text" name="contact_email" maxlength="50" placeholder="Email Address" /><br />
Subject:<br /><input class="contact_subject" type="text" name="contact_subject" maxlength="50" placeholder="Subject Line" /><br />
Message:<br /><textarea class="message_area" name="contact_message" rows="10" cols="50" maxlength="1000" placeholder="Message ..." /></textarea><br />
<input class="submit_button" name="submit_button" type="submit" value="Send" />
</form>
';
I tried searching for the answer and the only thing I found was adding:
<?php if(isset($contact_name)) { echo $contact_name; } ?>
This however does not work for me as my form is within a PHP echo and I'm trying to make a basic wordpress plugin. Whenever I bring the form outside the echo and , the style messes up and the form style itself breaks. So I was wondering if I can keep my form inside my echo along with a placeholder and be able to cache user inputs so when an error displays cause they didn't fill one of the spots out, it won't erase everything.
Thank you.
Then, just drop the echo and switch to HTML mode:
?>
<form method="post">
Name:<br /><input ... value="<?php echo (isset($contact_name) ? htmlspecialchars($contact_name, ENT_QUOTES, 'UTF-8') : ''; ?>" />
...
<?php
If you need this as a string, you could use output buffering:
ob_start();
?>
<input ... />
<?php
echo ob_get_clean();

I am creating a pizza ordering site with php. Now I want to echo the variable passed through the URL within the form. I know how to retrieve this data: <?php echo $_GET["numpizzas"]; ?>. But I don't know the proper way to add it to my html form field. any help is much appreciated
<?php
echo
'<form action="pizza.php" method="post">
<h1>Thanks for Ordering. Please submit your delivery info.</h1>
<label>Name:</label> <input type="text" name="name">
<label>Address:</label> <input type="text" name="address">
<label>Phone:</label> <input type="text" name="phone">
<label>Money: </label><input type="text" name="money" value="<?php echo "hi"; ?>" >
//Money field does not populate with number, I just see <?php echo $_GET[
<label>Feedback:</label> <input type="text" name="feedback">
<input type="submit" value="Submit">
</form>';
?>
<?php echo $_GET["numpizzas"]; ?>
I also tried storing the integer in a variable $howmanypizzas = $_GET["numpizzas"]; ?>but it still doesn't show up as the field value.
<?php echo $_GET["numpizzas"]; ?> does not only retrieve the data. echo also outputs it to the html response (the screen)
since you are allready passing your html with an ECHO, you can do:
<?php
echo
'<form action="pizza.php" method="post">
<h1>Thanks for Ordering. Please submit your delivery info.</h1>
<label>Name:</label> <input type="text" name="name">
<label>Address:</label> <input type="text" name="address">
<label>Phone:</label> <input type="text" name="phone">
<label>Money: </label><input type="text" name="money" value="'.$_GET["numpizzas"].'" >
<label>Feedback:</label> <input type="text" name="feedback">
<input type="submit" value="Submit">
</form>';
?>
Explanation: echo is a function that recieves a string and outputs it to html.
So, with the concatenation operator . you can inject the $_GET["numpizzas"] variable into your html, as a string, and pass it to the echo function, wich outputs it to the browser.
Another way to solve it is to only invoke PHP where you need to process your logic, just like #pavithra answer, wich also works.
You're already echoing and trying to echo inside of that. You need to concatenate your variable with the string that you are echoing, see PHP Strings:
echo
'<form action="pizza.php" method="post">
<h1>Thanks for Ordering. Please submit your delivery info.</h1>
<label>Name:</label> <input type="text" name="name">
<label>Address:</label> <input type="text" name="address">
<label>Phone:</label> <input type="text" name="phone">
<label>Money: </label><input type="text" name="money" value="' . $_GET["numpizzas"] . '">
<label>Feedback:</label> <input type="text" name="feedback">
<input type="submit" value="Submit">
</form>';
You might also consider Heredoc syntax.
<input type="text" name="money" value="<?php echo $_GET["numpizzas"]; ?>" />
but i dont get why do you get this is as a get variable.hope this works
<form action="pizza.php" method="post">
<h1>Thanks for Ordering. Please submit your delivery info.</h1>
<label>Name:</label> <input type="text" name="name">
<label>Address:</label> <input type="text" name="address">
<label>Phone:</label> <input type="text" name="phone">
<label>Money: </label> <input type="text" name="money" value="<?php echo $_GET["numpizzas"]; ?>" />
<label>Feedback:</label> <input type="text" name="feedback">
<input type="submit" value="Submit">
</form>
I have an HTML form that looks like this:
<form method="POST" action="ideal_test.php">
<input type="text" name="member[email]" placeholder="email" /><br />
<input type="text" name="member[country_code]" placeholder="country code" /><br />
<input type="text" name="member[first_name]" placeholder="first name" /><br />
<input type="text" name="member[last_name]" placeholder="last name" /><br />
<input type="text" name="member[street]" placeholder="street" /><br />
<input type="text" name="member[house_nr]" placeholder="house number" /><br />
<input type="text" name="member[houseNrExtension]" placeholder="house number addition" /><br />
<input type="text" name="member[postcode]" placeholder="postcode" /><br />
<input type="text" name="member[city]" placeholder="city" /><br />
<input type="text" name="member[phone]" placeholder="phone number" /><br />
<input type="text" name="member[birthday]" placeholder="birthday" /><br />
<input type="text" name="member[gender]" placeholder="gender" /><br />
<input type="text" name="member[ideal_bank]" placeholder="iDeal bank" /><br />
<input type="hidden" name="payment" value="ideal" />
<input type="submit" value="Test iDeal API call" />
The reason the form has been made this way is because I use an API that has to receive the data in this format. When I change the form action to the API URL, it works, however, sometimes I have to handle the form data myself with my own PHP and I don't know how I should process this form with PHP.
This is what I've tried:
$data = $_POST[ 'member' ];
foreach( $data AS $row ) {
echo $row . '<br />';
}
This shows all the data nicely separated by the <br />. However, I need to access each input separately, so I've tried this to achieve that:
foreach( $data AS $row ) {
echo $row['email'] . '<br />';
}
When I do this, it displays the first letter of each input, also separated by <br />. How can I loop through the member[] array and get every input separately?
$data is an array. So if you want to access each input separately You don't need to do it in foreach loop. You simply print it as normal array variable. Like this:
<?php
echo $data['email'];
echo $data['first_name'];
// Like this.
?>
I wish every time I reload or refresh the page. The disabled textbox still disabled. Because my purpose is to modify the textbox once time and then it will be disabled forever. Is this possible?
Below is my code
<tr>
<td><?php echo $lang_txt['leader_id'][$lang]; ?></td>
<td>:</td>
<td><?php if($_POST['txtLeaderID'] == ""){?><input type="text" name="txtLeaderID" id="txtLeaderID" style="width:400px;" value="<?php echo $merchant['LeaderID']; ?>" maxlength="20" /><?php }
else
{
?>
<input type="text" disabled="disabled" name="txtLeaderID" id="txtLeaderID" style="width:400px;" value="<?php echo $merchant['LeaderID']; ?>" maxlength="20" /><?php
}
?>
</td>
</tr>
Your variant will be worked with
if(!$_POST['txtLeaderID']){echo('<input type="text" name="txtLeaderID" id="txtLeaderID" style="width:400px;" value="'.$merchant['LeaderID'].'" maxlength="20" />')} else {echo('<input type="text" disabled="disabled" name="txtLeaderID" id="txtLeaderID" style="width:400px;" value="'.$merchant['LeaderID'].'" maxlength="20" />')}
For example:
<?php
if (!$_POST['username']){
echo('
<form action="'.$_SERVER['REQUEST_URI'].'" method="post">
Name: <input type="text" name="username" /><br />
Email : <input type="text" name="email" /><br />
<input type="submit" name="submit" value="Send POST!" />
</form>
');}
else{
echo('
<form>
Name: <input type="text" name="username" disabled="disabled"/><br />
Email : <input type="text" name="email" disabled="disabled"/><br />
</form>
');}
?>
But it didn't work, if we open it in a new tab. You must save this propery anywhere (session, cookie, sql)and check the stored values. it will be work in a new tab.
For example with session:
<?php
session_start();
if (!isset($_SESSION['data'])) {
$_SESSION['data'] = true;
echo('
<form action="'.$_SERVER['REQUEST_URI'].'" method="post">
Name: <input type="text" name="username" /><br />
Email : <input type="text" name="email" /><br />
<input type="submit" name="submit" value="Send POST!" />
</form>
');}
else{
echo('
<form>
Name: <input type="text" name="username" disabled="disabled"/><br />
Email : <input type="text" name="email" disabled="disabled"/><br />
</form>
');}
?>
if(isset($_POST['submit'])){
$domain=$_POST['domain'];
$fname=$_POST['fname'];
$sname=$_POST['sname'];
$tel=$_POST['tel'];
if($domain==""){
$error="<h4>Enter Domain </h4>";
}elseif($fname == ""){
$error="<h4>Enter Firstname </h4>";
}elseif($sname == "")
{
$error="<h4 >Enter Surname</h4>";
}elseif($tel=="")
{
$error="<h4 >Enter telephono no</h4>";
}
else {
$sql11=mysql_query("INSERT INTO domain VALUES('','$domain','$fname','$sname','$tel','$mobile','$email','$company','$address','$city','$country','$pcode','$tele',
'$fax','$qus','$ans')");
echo $sql;
$db->query($sql);
}
}
<div><?php echo $error; ?></div>
<form action="" method="post" name="classic_form" id="classic_form">
<div><h4>Personal details:</h4></div><div style="margin-left: 109px;">
<div>Domain</div>
<input type="text" name="domain" id="domain" value="" />
<div>First name: </div>

<div>Surname:</div>
<input type="text" name="sname" id="sname" value="" />

</form>
In my registration page, i used php validation. After the user submit the form if it shows validation errors it also resets all the fields. How can i resolve this problem? Without reset the fields i have to show the php validation errors. I also used in each input value. But it shows
"Notice: Undefined index: domain in D:\xampp\htdocs\deena\domainreg.php on line 82" . Please help me to resolve this problem
<input type="text" name="domain" id="domain" value="<?php echo isset($domain) ? $domain : ''; ?>" />
You have to pass all your values to php, and send back to html to feed your fields.
Its not 'resetting your fields' .. Your form is being submitted, hence the page is being reset and fields are therefore loading empty. Place the $_POST[] values in the field values upon page load:
<input type="text" name="domain" id="domain" value="<?php echo $domain ?>" />
<div>First name: </div>
<input type="text" name="fname" id="fname" value="<?php echo $fname?>" />
<div>Surname:</div>
<input type="text" name="sname" id="sname" value="<?php echo $sname?>" />
<div>Telephone:</div>
<input type="text" name="tel" id="tel" value="<?php echo $tel?>" />
Simple. Just add the variables to the input values:
<input type="text" name="domain" id="domain" value="<?php echo $domain; ?>" />
You should also protect the outputted value, against cross site scripting:
<input type="text" name="domain" id="domain" value="<?php echo htmlspecialchars($domain); ?>" />
In the value field:
<input type="text" name="domain" id="domain"
value="<?php if(isset($_POST['domain'])){echo $_POST['domain'];} ?>">
Didn't test it. But i think it should work.
In input tag add the php value as like value="" So that it will echo if the variable is posted or it will show the empty one
I can't seem to figure out how to make this script write data to the section of the file. Here is an excerpt of the code that applies:
$file = $url.'.php';
if (!$file_handle = fopen($file,"a+"))
{
echo $lang['cannot_open_file'];
}
if (!fwrite($file_handle,stripslashes(html_entity_decode($data))))
{
echo $lang['file_is_not_writable'];
}
fclose($file_handle);
echo ($lang['success']);
echo ('<meta http-equiv="Refresh" content="4;url='.$url.'.php" />');
}
}
?>
<form action="<?php echo $url;?>.php" method="post">
<?php echo $lang['name']?> <span style="font-weight:100;">(<?php echo $lang['required']?>)</span>:<br />
<input class="textfield" type="text" name="name" value="" /><br />
<?php echo $lang['website']?> <span style="font-weight:100;">(<?php echo $lang['without_http'];?>)</span>:<br />
<input class="textfield" type="text" name="site" value="" /><br />
<?php echo $lang['message']?>:<br />
<textarea class="textarea" rows="2" cols="25" name="message"></textarea><br />
<img src="captcha-image.php" alt="Image verification" /> <br />
<?php echo $lang['value_from_the_image'];?>:<br />
<input class="textfield" type="text" name="img_ver" value="" /><br />
<input type="reset" name="reset" value="<?php echo $lang['reset'];?>" />
<input type="submit" name="send" value="<?php echo $lang['send'];?>" />
</form>

Would anyone mind helping me out on this one? It would be much appreciated.
Use file get contens to retrieve the contens first.
Then use preg_replace to find where or what you want to be replaced.
Then rewrite the file with the new content.
