the sample site is this http://bit.ly/1gKGoN0
I have a problem on the loop of getting the value from the textboxes
i declared the form like this
<?php for($i=1;$i<=15;$i++){ ?> <input type="text" name="<?php echo
"you_item".$i.""?>" /> <?php } ?>
but the problem now is i cant get the value from the textboxes where i forwarded to $you_item[$i].
the site that i made doesnt have a loop. i coded the $you_item1 upto 15 because i have 15 textboxes.
can someone help me out?
try to change,
<?php for($i=1;$i<=15;$i++){ ?> <input type="text" name="<?php echo
"you_item".$i.""?>" /> <?php } ?>
to
<input type="text" name="you_item[]" />

Hey I'm currently having a problem with trying to make my input button have a value of the id / server that I need and it showing a different value this is how my code currently looks I know the HTML and forms are invalid I will be refactoring it however I'm trying to get a server identifier and a id identifier to cross to another page
<?php
$propertyType = $xmlDom1->getElementsByTagName('PropertyType');
$rent = $xmlDom1->getElementsByTagName('rates');
$rooms = $xmlDom1->getElementsByTagName('rooms');
//$server = $xmlDom1->getElementsByTagName('server');
$propertyServer = $xmlDom1->getElementsByTagName('Property');
$propertyID = $xmlDom1->getElementsByTagName('Property');
$imageURL = $xmlDom1->getElementsByTagName('url');
$imageAlt = $xmlDom1->getElementsByTagName('altText');
$server = $propertyID->item($i)->getAttribute('server');
echo '<form action="level5Details.php" method="get" enctype="application/x-www-form-urlencoded">';
echo '<table><th>Type:</th><th>Rent:</th><th>Rooms:</th><th>Server</th>';
$records = $xmlDom1->documentElement->childNodes;
for ($i = 0; $i < $records->length; $i++) {
echo "<tr><td>".$propertyType->item($i)->nodeValue."</td>";
echo "<td>".$rent->item($i)->nodeValue."</td>";
echo "<td>".$rooms->item($i)->nodeValue."</td>";
echo "<td>".$propertyServer->item($i)->getAttribute('Server')."</td>";
echo '<td><img src="data:image/jpeg;base64,'.$imageURL->item($i)->nodeValue.'" alt="'.$imageAlt->item($i)->nodeValue.'"></img></td>';
?>
<td>
<button class="submit" type="submit" value="<?php echo $propertyID->item($i)->getAttribute('pid'); ?>" name="submit22">something </button>
</td>
</tr>
<?php
}
?>
</form>
If you are trying to generate lots of form each with just a button then you need to put the form in a table cell like this
It might also be useful to place the data items you want to pass in hidden fields rather than try and put 2 data items in the button value
<?php
$propertyType = $xmlDom1->getElementsByTagName('PropertyType');
$rent = $xmlDom1->getElementsByTagName('rates');
$rooms = $xmlDom1->getElementsByTagName('rooms');
//$server = $xmlDom1->getElementsByTagName('server');
$propertyServer = $xmlDom1->getElementsByTagName('Property');
$propertyID = $xmlDom1->getElementsByTagName('Property');
$imageURL = $xmlDom1->getElementsByTagName('url');
$imageAlt = $xmlDom1->getElementsByTagName('altText');
$server = $propertyID->item($i)->getAttribute('server');
echo '<table><th>Type:</th><th>Rent:</th><th>Rooms:</th><th>Server</th>';
$records = $xmlDom1->documentElement->childNodes;
for ($i = 0; $i < $records->length; $i++) {
echo "<tr><td>".$propertyType->item($i)->nodeValue."</td>";
echo "<td>".$rent->item($i)->nodeValue."</td>";
echo "<td>".$rooms->item($i)->nodeValue."</td>";
echo "<td>".$propertyServer->item($i)->getAttribute('Server')."</td>";
echo '<td><img src="data:image/jpeg;base64,'.$imageURL->item($i)->nodeValue.'" alt="'.$imageAlt->item($i)->nodeValue.'"></img></td>';
$pid = $propertyID->item($i)->getAttribute('pid');
?>
<td>
<form action="level5Details.php" method="get" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="pid" value="<?php echo $pid;?>">
<input type="hidden" name="server" value="<?php echo $server;?>">
<button class="submit" type="submit" value="submit" name="submit22">something</button>
</form>
</td>
</tr>
<?php
}
?>
If you just want the button to carry all the data and have only one form you will have to package the 2 data items into one string and sent it as the value of the button
<?php
$propertyType = $xmlDom1->getElementsByTagName('PropertyType');
$rent = $xmlDom1->getElementsByTagName('rates');
$rooms = $xmlDom1->getElementsByTagName('rooms');
//$server = $xmlDom1->getElementsByTagName('server');
$propertyServer = $xmlDom1->getElementsByTagName('Property');
$propertyID = $xmlDom1->getElementsByTagName('Property');
$imageURL = $xmlDom1->getElementsByTagName('url');
$imageAlt = $xmlDom1->getElementsByTagName('altText');
$server = $propertyID->item($i)->getAttribute('server');
echo '<form action="level5Details.php" method="get" enctype="application/x-www-form-urlencoded">';
echo '<table><th>Type:</th><th>Rent:</th><th>Rooms:</th><th>Server</th>';
$records = $xmlDom1->documentElement->childNodes;
for ($i = 0; $i < $records->length; $i++) {
echo "<tr><td>".$propertyType->item($i)->nodeValue."</td>";
echo "<td>".$rent->item($i)->nodeValue."</td>";
echo "<td>".$rooms->item($i)->nodeValue."</td>";
echo "<td>".$propertyServer->item($i)->getAttribute('Server')."</td>";
echo '<td><img src="data:image/jpeg;base64,'.$imageURL->item($i)->nodeValue.'" alt="'.$imageAlt->item($i)->nodeValue.'"></img></td>';
$dataPackage = $propertyID->item($i)->getAttribute('pid') . ':' . $server;
?>
<td>
<button class="submit" type="submit" value="<?php echo $dataPackage;?>" name="submit22">something</button>
</td>
</tr>
<?php
}
</table>
</form>
?>
Now in the receiving form unpack the data for use
<?php
// usual checks for things existing
list($pid, $server) = explode(':', $_GET['submit22'];
So i have a little problem that i cant figure out and not sure how to do it
so i have a loop that creates form boxes and im gonna send all of them to a excel file(but thats later)
now i just want to create all variables in the loop
here is the loop with 1 textbox just to show
<?php
$i=1;
while ($i<=31){
?>
<input type = "text" name="day" />
<br />
<?php
$i=$i+1;
}
?>
so now how do i create a unique name for each box? or whats the best way to do it i read that array, fromarray is good at it if so im not good with arrays so how do i do it?
Change your input name like day[]
<?php
$i=1;
while ($i<=31){
?>
<input type = "text" value="day<?php echo $i; ?>" name="day[]" />
<br />
<?php
$i++;
}
?>
When you process form value with GET/POST like bellow (My example with POST) :
<?php
$days = $_POST['day'];
foreach($days as $day) {
echo $day;
}
?>
Or Like this :
<input list="day" name="day" class="listbox">
<datalist id="day">
<?php
$i=1;
while ($i<=31){
?>
<option value="day<?php echo $i; ?>">Day <?php echo $i; ?></option>
<?php
$i++;
}
?>
</datalist>
You can do this way
<?php
$i=1;
while ($i<=31){
echo '<input type = "text" name="day' . $i .'" /><br />';
$i=$i+1;
}
?>
this is a good place to use a for loop instead of the while loop:
<?php
for($i = 1; $i <= 31; $i++) {
?>
<input type = "text" name="day-<?= $i ?>" />
<br />
<?php
}
?>
Try this :)
$i=1;
while ($i<=31){
echo '<input type = "text" name="Random' . $i . '" /><br />';
$i++;
}
?>
And btw. you can do operations on variables much easier like this Operators
I want to create limit input tag with php for loop an get inputs values. My sample code is this:
<?php
$limit = 10;
for ($i=1; $i<=$limit; $i++) { ?>
<input name="<?php echo $i ?>" type="text" /><br>
<?php } ?>
Is my code correct? How can I get input values?
You can try my script.
<?php
$limit = 10;
?>
<form method="post">
<?php
for ($i = 1; $i <= $limit; $i++) {
?>
<input name="anything[]" type="text" /><br>
<?php } ?>
<input type="hidden" name="op" value="sent" />
<input type="submit" value="submit" />
</form>
<?php
if (!empty($_POST["op"])) {
for ($i = 1; $i <= $limit; $i++) {
if (strlen($_POST["anything"][$i]) !== 0) {
?>
<p>The value of the <?php echo $i; ?> text field is: <?php echo $_POST["anything"][$i]; ?>
<?php
} else {
?>
<p><?php echo $i; ?> was not set.</p>
<?php
}
}
}
Looks alright but I would use an array as the input name. For example:
<?php
$limit = 10;
for ($i=1; $i<=$limit; $i++) {
?>
<input name="number[<?php echo $i; ?>]" type="text" /><br>
<?php
}
?>
That way in the back end you can just loop through the number array like so.
foreach ($_POST['number'] as $key => $value) {
// Do stuff
}
Your code should render 10 html input fields with name 1, 2, 3, ... 10 correctly
To get input values, wrap your input fields in a form element with an action pointing to the php script in which you want to read the values (e.g. action="myscript.php").
(You should add a input type="submit" to have a way to submit the form. I assume you know HTML good enough to create a simple form.)
The script invoked by submitting the form (e.g. myscript.php) will now be able to read the values using the $_GET array. See http://php.net/manual/de/reserved.variables.get.php
You could print the values like so:
<?php
for($i=1;$i<=10; $i++) {
echo $i . ' : '. $_GET[$i];
}
?>
Edit: As #David Jones mentioned it would be better to use an array as input name
Hey I am new to PHP and I am trying to take values from the user that were put into a form for a game. Every time the user enters text and clicks submit it should add it to the array. Every time it will show at the bottom of the page all the guesses currently in a ordered list until the user gets the right answer and wins.
<?php
$count =0;
$guesses = array();
if(isset($_POST['submit']))
{
$count = $_POST['count'];
for($r =0; $r < $count; $r++)
{
$guesses[$r] = $_POST['word'];
}
?>
<h3>Guess the word I'm thinking</h3>
<form action = "<?php echo $_SERVER['PHP_SELF'] ?>" method = "post">
<input type = "text" name = "word" value = "<?php echo $tell; ?>"/>
<input type = "hidden" name = "count" value = "<?php $count +=1;?>"/>
<input type = "submit" name ="submit" value = "Make a Guess"/>
</form>
<ol>
<?php
for($t=0; $t < $count; $t++)
{
?>
<li><?php echo $guesses[$t];?></li>
<?php
}
?>
</ol>
I keep getting a Undefined offset: 0. I did some reading and I know it has something to do with either me filling the array wrong or calling the index wrong. Hope you can help show me how to resolve this problem. Thank you.
The output would be similar to:
Your guesses:
1. blue
2. red
etc
Look if you don't want to use Session variable then you have to set the values enter by the user in the hidden input tag. Below is the code you might required to get your specific result:
<?php
$guesses="";
if(isset($_POST['submit']))
{
$guesses= $_POST['count']." ".$_POST['word'];
}
?>
<h3>Guess the word I'm thinking</h3>
<form action = "<?php echo $_SERVER['PHP_SELF'] ?>" method = "post">
<input type = "text" name = "word" value = "Word"/>
<input type = "hidden" name = "count" value = "<?php echo $guesses;?>"/>
<input type = "submit" name ="submit" value = "Make a Guess"/>
</form>
<ol>
<?php
$count = explode(" ", $guesses);
foreach($count as $val)
{
if($val!= ''){
?>
<li><?php echo $val;?></li>
<?php
}
}
?>
</ol>
EDITED:
Problem was that you foremost did not echo the $count in your form, you simply incremented it. So the post variable would be empty. Also, increment it after you add to the array instead of in the post.
<?php
if( !isset( $count ) ){
$count =0;
}
$guesses = array();
if(isset($_POST['submit'])) {
$guesses[$count] = $_POST['word'];
$count++;
}
?>
<h3>Guess the word I'm thinking</h3>
<form action = "<?php echo $_SERVER['PHP_SELF'] ?>" method = "post">
<input type = "text" name = "word" value = "<?php echo $tell; ?>"/>
<input type = "submit" name ="submit" value = "Make a Guess"/>
</form>
<ol>
<?php
for($t=0; $t < count( $guesses); $t++)
{
?>
<li><?php echo $guesses[$t];?></li>
<?php
}
?>
</ol>
Try this code:
<?php
$guesses = array();
if(isset($_POST['submit']))
{
if($_POST['guesses'] != '')
$guesses = explode('|', $_POST['guesses']);
if(trim($_POST['word']))
$guesses[] = trim($_POST['word']);
}
?>
<h3>Guess the word I'm thinking</h3>
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
<input type="text" name= "word" value="" />
<input type="hidden" name="guesses" value="<?php echo count($guesses)? implode('|',$guesses):''; ?>" />
<input type="submit" name="submit" value="Make a Guess" />
</form>
<ol>
<?php foreach($guesses as $guess) { ?>
<li><?php echo $guess;?></li>
<?php } ?>
</ol>
I've problem with multiple form at one page. At page index I include 4 forms
include('./poll_1a.php');
include('./poll_2a.php');
include('./poll_3a.php');
include('./poll_4a.php');
The form code at every poll page is the same. I include some unique markers ($poll_code) for every scripts but the effect is when I use one form - the sending variable are received in the others. But I would like to work each form individually.
The variable $poll_code is unique for every script -> 1 for poll_1, 2 for poll_2 etc.
The same situation is with $cookie_name
$cookie_name = "poll_cookie_".$poll_code;
than, as I see, cookies have different names.
$poll_code = "1"; // or 2, 3, 4
?>
<p>
<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post" name="<?php echo $poll_code; ?>">
<input type="hidden" name="poll_cookie_<?php echo $poll_code; ?>" value="<?php echo $poll_code; ?>">
<table>
<?php
//print possible answers
for($i=0;$i<count($answers);$i++){
?><tr><td style="\text-allign: left;\"><input type="radio" name="vote_<?php echo $poll_code; ?>" value="<?php echo $i; ?>"> <?php echo $answers[$i]; ?></td></tr><?php
}
echo "</table>";
echo "<br>";
if ($_COOKIE["$cookie_name"] == $poll_code ) {
echo "<br> nie można głosować ponownie ...";
} else {
?>
<p><input type="submit" name="submit_<?php echo $poll_code; ?>" value="głosuj !" onClick="this.disabled = 'true';"></p>
<?php
}
?>
</form>
</p>
Q: how to make this forms to work individually at one page?
//------------------- EDIT
the receiving part of the script
$votes = file($file);
$total = 0;
$totale = 0;
$poll_cookie = 0;
if (isset($_POST["vote_$poll_code"]) && isset($_POST["poll_cookie_$poll_code"])) {
$vote = $_POST["vote_$poll_code"];
$poll_cookie = $_POST["poll_cookie_$poll_code"];
}
//submit vote
if(isset($vote)){
$votes[$vote] = $votes[$vote]+1;
}
//write votes
$handle = fopen($file,"w");
foreach($votes as $v){
$total += $v;
fputs($handle,chop($v)."\n");
}
fclose($handle);
Of course, the $file have the unique declaration too (at top of the script, under the $poll_code declaration).
$file = "poll_".$poll_code.".txt";
I think the issue might be that <?php echo $poll_code; ?> is outside the loop so maybe that it's always using the same value assigned to it, maybe put it inside the loop
