How can I loop numbers inside a textbox whenever page is refresh? in PHP
<input type="text" name="name1" value="loophere">
I want a textbox automatically have a value number whenever I refresh a page.
I need to used this for a column in my database and I want it automatically. I already have one column auto_increment in my database. Big thanks.
Use rand()
<input type="text" name="name1" value="<?php echo "1".rand();?>">
http://php.net/manual/en/function.rand.php
OR Use str_shuffle()
<?php
$string = "123456789AaBbCcDdEeFfGgHhIiJjKkLlMmNnPpQqRrSsTtWwXxYyZz"; //You can use any string
$key_len = "5";
$string_shuffle = str_shuffle($string);
$session_key = str_shuffle(substr($string_shuffle, 3, $key_len));
?>
<input type="text" name="name1" value="<?php echo $session_key;?>">

I'm working on a formular, but for the moment I just want to insert into an array my elements (I have books and authors).
I can display my books with author (name + surname) with the foreach, but I can't add more elements.
Here is the code with the form.
<H1>Exercice 2</H1>
<form method="POST">
<label for"code" >Number :</label>
<input id="code" name="code" type="number" />
<label for"title">Title :</label>
<input id="title" name="title" type="text" />
<label for"author" >Author :</label>
<input id="author" name="author" type="text" />
<button type="input" type="submit">Ok</button>
$title = $_POST['title'];
$code = $_POST['code'];
$author = $_POST['author'];
$book = array();
$book['code'] = 123;
$book['title'] = "Legendes";
$book['author'] = array("David", "Gemmel");
foreach($book as $value){
$book['key'] = $value;
var_dump($book);
if (is_array($value)) {
foreach($value as $otherValue) {
echo($otherValue);
}
} else {
echo($value);
}
}
I did some searcch, but I don't think it works, it's using the array_push() method with the POST, but I don't know where I can manipulate my form into the array.
If you want some details, I'll be happy to do that =) I'm working on it, if i have some news, you will know =)
Have a nice day =)
1) Assignments are in reverse. Correct way:
$myVar = $myValue
2) You need to set the name attribute in your inputs in order to be sent:
<input id="code" type="number" name="code" />
Then you can access them like:
$_POST['code']
3) To add an element by key in an array, use:
$array['key'] = $value;
Your Exercise 2 have some mistakes :
First, your HTML inputs must have the name attribute to be retrieved by post:
<h1>Exercice 2</h1>
<form method="post">
<label>
<input name="code" type="number" />
</label>
<button type="submit">Ok</button>
</form>
With PHP, you can access to any input value using the name:
$code = $_POST['code'];
Now, I think you want to "add" several books using this HTML form without a storage system. The problem is you can not do this if for every a new request since all the elements you have in your array will be deleted each time you run a new post request. To keep this information you need to use some persistent storage system as a database or others.
Since you seem to want to keep the information for each book together, you need to use a multidimensional array - hence, you'll need to redo the whole thing. Here's a suggestion:
Form:
<h2>Exercice 2</h2>
<form method="post">
<label for"code">Number :</label>
<input id="code" name="code" type="number">
<label for"title">Title :</label>
<input id="title" name="title" type="text">
<label for"author-firstname">Author First Name:</label>
<input id="author-firstname" name="author-firstname" type="text">
<label for "author-lastname">Author Last Name:</label>
<input id="author-lastname" name="author-lastname" type="text">
<input type="submit" name="submit_book" value="Ok">
</form>
Fixed the name-problems, changed the heading (you never, ever use H1 for a form, H1 is strictly used for the site-wide heading/logo/name of site). Also changed the button into a simple input type="submit".
$title = $_POST['title'];
$code = $_POST['code'];
$author = $_POST['author'];
$book = []; // changed this to modern PHP version array assignment
$book[0]['code'] = 123;
$book[0]['title'] = "Legendes";
$book[0]['author-firstname'] = "David";
$book[0]['author-lastname'] = "Gemmel"; // no reason to assign a separate array for first and last name, just use two array-keys
for ($c = 0; $c <= count($book); $c++) { //changed this to a for, counting the amount of entries in the $book array
echo 'Title: '.$book[$c]['title'];
echo 'Author: '.$book[$c]['author-firstname'].' '.$book[$c]['author-lastname'];
} // the content should probably be wrapped in a container of some sort, probably a <li> (and then a <ul>-list declared before the for-loop)
Now. None of this has anything to do with putting stuff INTO the array. That would be something like this (there isn't even a point of assigning the $_POST-variables for the code you posted. But, you can do something like this:
if (isset($_POST['submit_book'])) {
$title = $_POST['title'];
$code = $_POST['code'];
$author-firstname = $_POST['author-firstname'];
$author-lastname = $_POST['author-lastname'];
// however, if all you're doing is putting this into the array, no need to assigne the $_POST to variables, you can just do this:
$temp_array = ['code'=>$_POST['code'],'title'=>$_POST['title'],'author-firstname'=>$_POST['author-firstname'],'author-lastname'=>$_POST['author-lastname']];
$book[] = $temp_array;
}
So, that would replace the assigned variables at the beginning of your code.
I have three inputs type text in an HTML page and a button which if clicked duplicate each text box (Javascript) making them 6.
<input type="text" name="category[]">
<input type="text" name="quantity[]">
<input type="text" name="amount[]">
<button>Add more</button>
Which generate same inputs again:
<input type="text" name="category[]">
<input type="text" name="quantity[]">
<input type="text" name="amount[]">
A piece of code in Cakephp I have been trying:
$data = $this->request->data;
foreach($data['category'] as $index => $value){
$this->ModelName->save($value);
}
Trying to get two rows inserted at once with quantity, category and amount as columns. But it is not inserting and not giving any error.
Is there a way I can achieve this?
Thanks.
I'm not sure how your model works in cakephp, but you should be able to get a complete grouping of data like:
foreach($data['category'] as $index => $value){
$category = $value
$quantity = $data['quantity'][$index];
$amount = $data['amount'][$index];
// use the above 3 variables however you need to to persist the model
//$this->ModelName->save($value);
}
On a side note, you may want to consider reordering your html inputs to be like:
<input type="text" name="item[0][category]">
<input type="text" name="item[0][quantity]">
<input type="text" name="item[0][amount]">
And then maintain the next index, incrementing the numeric index of item for each additional group
This will allow you to iterate like:
foreach($data['item'] as $index => $group){
//$group['category'];
//$group['quantity'];
//$group['amount'];
}
Form:
<form method="POST" action="edit_work.php">
<input type="hidden" name="wid[]" size="1" value="<?php echo "$wid1" ?>" >
<input type="text" name="course[]" size="15" value="<?php echo "$course1" ?>" >
PHP:
extract($_POST);
for($i=0;$i<$count;$i++) {
echo $wid[$i];
echo $course[$i];
}
gives the wid values OK but not the text entered for the course names.
I have been through all forums for 2 days now. Any help? Thanks.
If you want your PHP to retrieve your data from the form, can't you name your text input "course", then get it inside your PHP with $_POST['course'] ?
What is your $count ?
Using brackets with your name attribute inside your input tag may be dangerous.
If you're using a list of inputs maybe you can define a text format like name="course#" where # is your index and then access it form your $_POST variable using $_POST['course'.$index]
You don't need to extract($_POST) in that case.
<input type="radio" name="package" value="SOME_VALUE_HERE">
I am using Joomla but i think its something related to PHP. I have a form on my website, and it has RADIO button , what i want is when the user submits the form with that RADIO BUTTON selected, in place of the value (SOME_VALUE_HERE) , i want something else to get stored in the database. That something should a 10-15 liner text. Can i make a $PHP variable and assign that 10-15 liner text to that variable and use it in place of the value=(SOME_VALUE_HERE).
Example :
<input type="radio" value="$phpvariable">
Where $phpvariable is a 10-15 liner text!
Hope you got my point!
You need to use php-tags and echo the php variable in the value of the input:
Assign value to php variable:
<?php $phpvariable = 'SOME LONG TEXT HERE'; ?>
The input:
<input type="radio" name="package" value="<?php echo $phpvariable; ?>">
You will also need a name for your input so that you can get the value
My suggestion would be to try:
<input type="radio" name="package" value="<?php echo htmlspecialchars($name); ?>">
If that does not work, just create a hidden field:
<input type="hidden" name="packageHidden" value="<?php echo htmlspecialchars($name); ?>">
function htmlspecialchars prevents XSS attacks as well.
<input type="text"
name='username'
onblur="if(this.value=='')this.value='Username';"
onfocus="if(this.value=='Username')this.value='';"
value="Username"
class="register"/>
This is the code that I am using but the way my code is setup I want the text to be viewable in the field before the user types in their information but the way the form is setup now the
value="<?php echo $db_first_name; ?>"
but the code i'm using needs
value="Username"
to display username in the field before clicked by user and put in their own information.
I tried
value="Username<?php echo $db_first_name; ?>"
But obviously that did not work. Any Ideas?

Try the placeholder attribute (valid as of HTML5):
<input type="text" name="username" id="username" placeholder="Username" value="<?= $db_first_name; ?>" />
Alternatively (in other words, if you want to support users whose browsers don't support HTML5), you can test to see whether the user already has a username entered. If it's null or an empty string, set the value to "Username" otherwise, set the value to the value of $db_first_name. Then change the onBlur event to check for the length of the value of the field, and if the length is zero, have it display "Username". Finally, change the onFocus event to listen for a mouse-click - when the user gives focus to the field, set the value to an empty string.
<input type="text" name="username" id="username" value="<?= $db_first_name == "" ? "Username" : $db_first_name ?>" onBlur="checkUsernameBlur(this, 'Username');" onFocus="checkUsernameFocus(this, 'Username');" />
<script type="text/javascript" language="javascript>
function checkUsernameBlur(inputObj, label) {
var strLen = inputObj.value.length;
if (strLen == 0) {
inputObj.value = label;
}
}
function checkUsernameFocus(inputObj, label) {
var value = inputObj.value;
if (value == label) {
inputObj.value = "";
}
}
</script>
To work in lower html versions not only in html5 change the Username text in all the three places to the wanted word or php variable
<input type="text" name='username' name='username' onblur="if(this.value=='')this.value='<?php echo $db_first_name; ?>';" onfocus="if(this.value=='<?php echo $db_first_name; ?>')this.value='';" value="<?php echo $db_first_name; ?>" class="register"/>
