I want to know how to make user enter some text inside a textarea then when he press the save button the text that he typed get saved inside a file here is my code :
<?php
header("location: add/Project.html" );
$handle = fopen("Project.html", "a");
foreach($_POST as $value) {
fwrite($handle, $value);
}
fclose($handle);
exit;
?>
This code works but with the <input> only for example here is my html Code :
<form action="add.php" method="post">
<textarea type="text" name="code" id="code" value="" ></textarea>
<input type="text" name="code" id="code" value="" /><input value="Submit" tabindex="4" type="submit" >
</form>
It will output only the text that was written in the <input>
Can you help me please !
Your textarea and input have the same name. To fix, give them different names:
<form action="add.php" method="post">
<textarea type="text" name="codetextarea" id="codetextarea" value="" ></textarea>
<input type="text" name="codeinput" id="codeinput" value="" />
<input value="Submit" tabindex="4" type="submit" />
</form>
(They also have identical ids, which is even illegal in XHTML)
If you have inputs with the same name (and that name doesn't end in []), then PHP will ignore all but one of them (as far as I can tell, this makes it unique among form processing libraries). Give them different names.
Alternatively, rename them to code[] and PHP will populate $_POST['code'] with an array. Then loop over that array instead of $_POST itself.
The two answers above mine have the point. Also, you don't need value attribute in <textarea>, because textarea's value comes from whatever is within opened and closed <textarea></textarea> tags. It is different than for <input> tags.
Also, when opening a file, you should specify another 'reading' property called binary ( a letter b ).
So it should look like
$handle = fopen('path_to_file.extension','ab');
This is for compatibility purpose
Try this
<form action="add.php" method="post">
<textarea name="codetextarea" id="codetextarea" value="" ></textarea>
<input type="text" name="codeinput" id="codeinput" value="" />
<input value="Submit" tabindex="4" type="submit" />
</form>

I am using dynamic form where user add more input text boxes for a certain field he want and the name of each box change with an increment like:
<form method="post" action="somescript.php">
<input type="text" name="textbox" />
<input type="text" name="textbox1" />
<input type="text" name="textbox2" />
<input type="text" name="textbox3" />
.... and so on
</form>
I want to echo these data following a loop:
<?PHP
$k=$_POST['counter']; //counter value coming as post variable
for($i=1$i<=$k;$k++){
echo $_POST['textbox'.$i]; //something like this......?
}
?>
Please reply.
Use array notation instead.
<form method="post" action="somescript.php">
<input type="text" name="textbox[]" />
<input type="text" name="textbox[]" />
<input type="text" name="textbox[]" />
<input type="text" name="textbox][" />
.... and so on
</form>
When the form is submitted, $_POST['textbox'] will then be an array, and you can loop over it:
foreach ($_POST['textbox'] as $textbox) {
echo $textbox;
}
I just came across this issue because I had blocks of data that needed to be created dynamically and
echo $_POST["textbox$i"];
worked without the concatenation in it. Let me know if this is bad practice, it works in my situation though. The array way didn't work for me. Sorry for posting this on a 3 year old question. I'm not sure if that's bad practice. Thanks.
I'm practicing form validation with JavaScript but when I try to retrieve the data from the page it submits to I can't get it.
form.html
<body>
Hello.<br />
<form onsubmit="return validate()" action="process.php" method="POST">
Enter name: <input type="text" id="name" /><br />
Enter phone number: <input type="text" id="number" /><br />
Enter password: <input type="password" id="paswd" /><br />
Is there anything else you would like to add: <input type="text" id="anything" /><br />
<input type="submit" value="Check Form" />
</form>
</body>
process.php
<?php
echo 'Here: '.$_POST['number']
?>
Whatever index I use I get " Undefined index: line 2". What am I doing wrong?
EDIT: So I can't use the id attribute I need the name? Is there anyway to prevent coding redundancy since the value of all names will be the same as the corresponding id?
You need name attribute in your fields
<input type="text" id="number" name="number" />
$_POST looks for the name attribute in the field to capture the field values and not id
Your inputs need the name of the element.
Such as:
<input type="text" id="number" name="number" />
The Php gets the form data looking these names, not the ids.
you forgot name of input:
<input type="text" id="number" name="number" />
You need to give your form elements names.
<input type="password" id="paswd" name="paswd" />
Interestingly names and ids share the same namespace. If you don't really need the ids, leave them be. Inside a validate function you can always access all elements with the elements object of the form.
// called onsubmit
var validate = function(e) {
if (this.elements["paswd"].value.length < 4) {
alert("password needs to have at least 4 characters");
return false;
}
return true
};
I usually append the input type to my ids to differentiate them from field names
<label for="paswd-txt">Password: </label>
<input type="text" name="paswd" id="paswd-txt" />
<label for="save-cb">Remember me: </label>
<input type="checkbox" name="save" id="save-cb" value="1"/>
So like Vitor Braga said your inputs need the name of the element, but you only need this if you are using PHP to hadle the values of form in the submit, if you are using javascript to validaate like you said your were praticing you can obtain the value like this:
document.getElementById("number").value
There are 10 boxes in my website that I fill up based on my needs. From php code I prefer not to check them one by one like this. Instead of that I thought it would be a good idea to put check marks in each boxes and if I fill something in input field it should be checked so I can check however many checkboxes are filled and know how many boxes are filled.
if ($input1) {$total = "1";
if ($input2) {$total = "2";
}
}
Anybody knows how can I put automatically check into a checkbox when I start typing anything in it ? But it should be unchecked back if I delete what I wrote before sending it. Or if you guys have a better idea that would be nice also.
Thank you !
you could do this in JavaScript. Basically if the number of input text is the same of the checkboxes then you could use this function for example:
function change() {
var input_lengths = document.getElementsByName("textArray[]");
for(var i= 0; i < input_lengths.length;i++) {
if(document.getElementsByName("textArray[]").item(i).value != "") {
document.getElementsByName("checkArray[]").item(i).checked = true;
}
}
}
and your html could be:
<input type="text" name="textArray[]" value="" />
<input type="text" name="textArray[]" value="" />
<input type="text" name="textArray[]" value="" />
<input type="text" name="textArray[]" value="AAA" />
<input type="checkbox" name="checkArray[]" value="" />
<input type="checkbox" name="checkArray[]" value="" />
<input type="checkbox" name="checkArray[]" value="" />
<input type="checkbox" name="checkArray[]" value="" />
<input type="button" value="test" onclick="javascript:change()" />
why don't you name your checkboxes as an array e.g.:
<input type="checkbox" name="boxes[1]" />
<input type="checkbox" name="boxes[2]" />
then you can loop through the array in php and check each one individually
This is how i understood your problem:
you have 10 text inputs
you want to know how many of them contain actual input when they are submitted
your idea was to assign a checkbox input to each text input so that the corresponding checkboxes are checked when an input has text and is unchecked when an input has no text
Something very quick and dirty. You might want to name you inputs with a square bracket, so that php interprets that parameter as an array. Then you can iterate over an array and if the values are set you can count.
<html>
<body>
<?php
if(isset($_POST['input'])) {
$count = 0;
foreach($_POST['input'] as $value) {
if($value) {
$count++;
}
}
echo $count;
}
?>
<form action="testinputs.php" method="post">
<input name="input[]" value="" type="text">
<input name="input[]" value="" type="text">
<input name="input[]" value="" type="text">
<input name="input[]" value="" type="text">
<input name="input[]" value="" type="text">
<input name="input[]" value="" type="text">
<input type="submit"/>
</form>
</body>
</html>
If you want to do that on the client side, than I'd take something like jQuery and look how many inputs on my page contain any text inside them.
Find below my form and the action page it submits to. The _POST array is empty. Not sure how. Please help.
index.php
<form method="post" action="track-them.php">
<input type="text" width="255" id="txt" />
<textarea id="ta" type="text" cols="25" rows="4"></textarea>
<input type="submit" id="check-button" value="Ok" />
</form>
track-them.php
<?php
include_once('../simple_html_dom.php');
print_r($_POST);
?>
Both fields txt & ta have values but the output I see when I click submit is:
Array ( )
Add name attribute to your form elements:
<form method="post" action="track-them.php">
<input type="txt" width="255" id="myurl" name="myurl" />
<textarea id="ta" name="ta" type="text" cols="25" rows="4"></textarea>
<input type="submit" id="check-button" value="Ok" />
</form>
Give your inputs a name. The browser passes the name attribute not the id.
If you put the print_r($_POST) above the inclution what is the result ?
Please add name attribute for each from element
I'm trying to build a form using php & jquery, but I'm a little confused as to what to do with the jquery portion of it...
Basically, when the user submits the first form, I want to direct them to the "next step" form, but I want to retain the values submitted from the first one in a hidden input field...
If someone can either show me how or point me to a good tutorial, I'd appreciate it...
I don't have any of the php or jquery yet, and this is just a simplified version of the html markup...
//first.php
<form name="form1" method="post" action="second.php">
<input type="text" name="name" value="" />Name
<input type="submit" name="step1" value="Next" />
</form>
//second.php
<form name="form2" method="post" action="process.php">
<input type="hidden" name="name" value="{$_POST['name']}" />
<input type="text" name="message" value="" />message
<input type="submit" name="step2" value="Finish" />
</form>
<input type="hidden" name="name" value="{$_POST['name']}" />
should be,
<input type="hidden" name="name" value="<?php echo $_POST['name']}; ?>" />
and also sanitize the input, if you want
I don't no if there is a better way to do that.
But, when I need to do such thing, I do in this way:
<script>
<?php
foreach($_POST as $key => $valule)
{
echo "$('$key').val('$value')";
}
?>
</script>
So, in your nextstep file, all you'll need to do is set up the hidden fields and then just loop through the post vars and set each one via jquery.
