I have a form that is being generated on the fly in PHP using the below ($theFeatures is a multidimensional array):
<?php
foreach($theFeatures as $theKey => $theValues) {
?>
<input type="text" value="<?php echo $theValues['Key']; ?>" name="theFeatures[<?php echo $theKey; ?>]['Key']" size="6" />
<input type="text" value="<?php echo $theValues['Value']; ?>" name="theFeatures[<?php echo $theKey; ?>]['Value']" /> <br />
<?php
}
?>
This should create two input boxes that look like this:
<input value="Type" name="theFeatures[4]['Key']" size="6" type="text" />
<input value="Bird Table" name="theFeatures[4]['Value']" type="text" />
How can I get the first part of the array ( [4] in the above example ) in jQuery so I can store that as a JavaScript variable and use it else where in my jQuery??
Cheers,
Andy
You could try just storing the value in a separate attribute on the input and then retrieving that attribute with jQuery.
Adding the new attribute to the input
<input type="text" value="<?php echo $theValues['Key']; ?>" name="theFeatures[<?php echo $theKey; ?>]['Key']" size="6" key="<?php echo $theKey; ?>"/>
Retrieving the attribute with jQuery
var key = $("input").attr("key");
Certainly T B's suggestion could work. You can also do the following to get all input boxes that have "Key" in the name and get the value in the first set of square brackets. This will get any input object with the name containing Key.
$("input[name*=Key]").each(function() {
var name = $(this).attr("name");
var key = name.substring(name.indexOf("[") + 1, name.indexOf("]");
//do whatever is needed with key
});

Here is my view
<?php for($i=0;$i<count($acb['def']);$i++) { ?>
<input type="text" name="xyz" value="<?php echo $abc['def'][$i]?>" />?>
Here is my controller
$xxx=$this->input->post('xyz')
Now when i submit the form the last value only gets posted to controller
then i found that the name is same for all fields so it takes last value , so i changed the input name as
name ='xyz[$i]'
Now i need to post values , How to post values with this
You need to send name as array rename it to 'xyz[]' here
<input type="text" name="xyz[]" value="<?php echo $abc['def'][$i]?>" />?>
You use to below code...
<?php for($i=0;$i<count($acb['def']);$i++) { ?>
<input type="text" name="xyz[]" value="<?php echo $abc['def'][$i]?>" />
?>
I generate a form, which mostly consists of input fields that are already populated with values from the db.
So I do this currently like so:
<input id="misc" name="misc" value="<?php echo $workout['misc']; ?>" />
But when I try and do this:
<input id="misc" name="misc" value="<?php echo set_value($workout['misc']); ?>" />
along with a validation rule, the form does reload itself, the error message does display BUT the form is reset
What am I doing wrong?
As per the manual:
Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function. The second (optional) parameter allows you to set a default value for the form. Example:
<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" />
The above form will show "0" when loaded for the first time.
Hence in your case:
<input id="misc" name="misc" value="<?php echo set_value('misc', $workout['misc']); ?>" />
OR
<input id="misc" name="misc" value="<?php echo set_value('misc'); ?>" />

I have a form with multiple text inputs that all have the same name. How would I process that with my PHP when the user submits the form?
HTML:
<input type="text" name="interest"/>
I've assumed you're using POST.
You would use
<input type="text" name="interest[]">
Then on the post page, you could use:
foreach($_POST['interest'] as $i){
echo $i. "<br>";
}
or whichever method you wanted to use to get the POST data.
You could also do something like:
<input type="text" name="interest[music]"/>
<input type="text" name="interest[food]"/>
You can then call this data by using:
<?php echo $_POST['interest']['music']; ?>
<input type="text" name="interest[]"/>
You should add square brackets. This triggers PHP to put them in an array like this:
HTML
<input type="text" name="interest[]"/>
<input type="text" name="interest[]"/>
PHP
//Get values
var_dump($_POST['interest']);
Use brackets in your input field to create an array of POST values:
<input type="text" name="interest[]"/>
<?php
var_dump($_POST['interest']); // will be an array
?>
I have 3 text fields and I want to pass the values after combining them using a hyphen.
<input type="text" name="val[]" />
<input type="text" name="val[]" />
<input type="text" name="val[]" />
Preferably help me with php implode option.
How do i retrieve it after submit ?
Thanks.
After sending the form, your values will be in $_POST['val'] or $_GET['val'] as an array, depending on the method of your form.
You can combine them simply by:
$hyphenated = implode("-", $_POST['val']); // or $_GET['val']
thanks. how do i change focus to next field once a field has max values:
See if this works:
<input type="text" name="val[]" onkeyup='checkVals("field1", "field2");' id='field1'>
<input type="text" name="val[]" onkeyup='checkVals("field2", "field3");' id='field2'>
<input type="text" name="val[]" id='field3'>
<script>
function checkVals(this_field, next_field){
var fieldval = document.getElementById(this_field).value;
var fieldlen = fieldval.length;
if(fieldlen > 10){ // you can change 10 to something else
document.getElementById(next_field).focus();
document.getElementById(next_field).select();
}
}
</script>
I tried $_POST['<?php echo $var ?>] but I should have known that it wouldn't be that easy.
The reason why I try to do is because I have several input boxes with values I take from a database and I'm trying to create an updation script where any of the input box values can be changed.
for example
<form action="process.php" method="post">
<?php
while($variable=mysql_fetch_array($sqlconnec))
{
?>
<input type="text" name="<?php echo $variable['col1']?>" value="<?php echo $variable['val'] ?>" />
<?php
}
?>
<input type="submit" />
</form>
Any help is appreciated.
I think that what you need is:
<input type="text" name="<?php echo $col; ?>" value="<?php echo $val; ?>" />
$_POST[$col] //this will have the input value defined above.
In process.php you have to do the same query as mentioned above. If you iterate through those results $_POST[$col] will contain the posted values.
You need to do like this:
<form action="process.php" method="post">
<?php
$variable = mysql_fetch_assoc($sqlconnec);
foreach($variable as $col => $val)
{
?>
<input type="text" name="<?php echo $col; ?>" value="<?php echo $val; ?>" />
<?php
}
?>
<input type="submit" />
</form>
Now, mysql_fetch_assoc gets you the database row in a associative array. Then, the code iterates each column in the row and displays the name/value pair for it. And yes, you were not closing the value tag correctly.
foreach($_POST as $k=>$v) {
//do something with $v or $_POST[$k]
}
I think that you want to change the name of the input to something that is constant.
For example:
<input type="text" name="testname" value="<?php echo $variable['val'] ? />
And then retrieve your variable like so:
$_POST['testname']
For example you could print the variable you sent in the input to test it like so:
echo $_POST['testname'];
You are not closing your input 'value' tag with ". Also your second php closing tag is incorrect.
<input type="text" name="<?php echo $variable['col1']?>" value="<?php echo $variable['val'] ?>" />
