PHP - Post Array Size Limit, But Not Mb

Hi Guys
I am using an htmlarea editor and when trying to add more than 1000 characters to this area it gives me an error. The html area editor opens a text file and then posts the changes and rewrites that text file.

Any way around this to make it unlimited?

I'm trying to add a file size limit to my upload form-code (below)

Is there a limit to how many items can be stored in an array?

My code looks in a directory of photos and writes the file names into the one-dimensional array.

I just switched from my test folder to my actual photo folder - about 600 photos - and when I ran my script with var_dump enabled, my array only goes up to 128 items (0-127).

I sure hope arrays aren't that wimpy?!

Each photo is about 1-2MB in size, but since I am only storing the file name, I would expect that I could easily store thousands of elements in this array.

What is going on?

 

Hi there, im really stuck here. I have a table of records that are selected from my db and put into an array and randomly chooses them, outputting the results .

Code: [Select]
<?php 
$count = 0;
while ($row = mysql_fetch_assoc($Ships4)){
$array[$count]['ShipID'] = $row['ShipID'];
$array[$count]['ShipName'] = $row['ShipName'];
$array[$count]['Dclass'] = $row['Dclass'];
$count++;

$total4 = count($array);
$random4 = rand(0,$total4 - 1);
$random_ship4 = $array[$random4];
$ShipID4 = $random_ship4['ShipID'];
echo $ShipID4;}
This all works fine, however I want to limit the number of random outputs from a number in a record in a different table.

So i added:
Code: [Select]
<?php
if ($count < $row_dclasscorella['Dclass4_totla']){ ?>
the number from the field is 2.

The trouble is that it doesnt take any notice and outputs the total number a random number for each record. It seems its not limiting it. How can i get this to work please???

Code: [Select]
$count = 0;
if ($count < $row_dclasscorella['Dclass4_totla']){
while ($row = mysql_fetch_assoc($Ships4)){
$array[$count]['ShipID'] = $row['ShipID'];
$array[$count]['ShipName'] = $row['ShipName'];
$array[$count]['Dclass'] = $row['Dclass'];
$count++;

$total4 = count($array);
$random4 = rand(0,$total4 - 1);
$random_ship4 = $array[$random4];
$ShipID4 = $random_ship4['ShipID'];
echo $ShipID4;}}?>
Thank You

Ok so I have someone needing me to write a php page(s) to basically check the current size of a file in a directory and display the current size and max allocated size then create a dynamically changing image to reflect those parameters(i.e. pise chart, bar graph, etc.) all called to an intranet page.

I work at a business where we upload OS images to a server file but that file is only allocated so much space. The problem we are running into is that we do not know when the space is full until all of our uploads fail.   We are attempting to create a visual representation of that space so that we know when to purge the space of the old temporary images.

I dont even know where to start on this .. would someone please point me in the direction of some code that would get me started on building this project? I have exhausted my efforts on Google and other PHP pages.. I am new to PHP so I may already be in over my head but I am adventurous and will try anything.

Thanx in advance

Hey folks! Happy what ever you are celebrating

I am trying to limit the number of characters to 200 that this array echos. I have tried a few things... I have tried using "substr($arr_tem, 0, 200)" but obviously it is not working... but I think I am close-ish. Any assistance would be great!
 
Code: [Select]
###print array###
echo (implode(", ", array_keys($arr_tem)));
Thanks!

Hi How can limit only required input fields cannot be empty.

<form name="test" method="post" action="test.php">
<label for="quest">
  <input type="text" name="quest" />  <!-- REQUIRED -->
</label>
<label for="answers">
  <input type="text" name="answers[]" /> <!-- REQUIRED -->
</label>
<label for="answers">
  <input type="text" name="answers[]" /> <!-- REQUIRED -->
</label>
<label for="answers">
  <input type="text" name="answers[]" />
</label>
<label for="answers">
  <input type="text" name="answers[]" />
</label>
<label for="answers">
  <input type="text" name="answers[]" />
</label>

<label for="submit">
  <input type="submit" name="submit" value="Submit" />
</label>
</form>

Following function working only on all empty input fields, i need help to enable button when required fields is not empty.

$(document).ready(function() {
    var $submit = $("input[type=submit]"),
        $inputs = $('input[name=quest], input[name=answers[]]');

    function checkEmpty() {

        // filter over the empty inputs
        return $inputs.filter(function() {
            return !$.trim(this.value);
        }).length === 0;
    }

    $inputs.on('keyup', function() {
        $submit.prop("disabled", !checkEmpty());
    }).keyup(); // trigger an initial blur
});

I have these two tables... schedule (gameid, homeid, awayid, weekno, seasonno) teams (teamid, location, nickname) This mysql query below gets me schedule info for ALL 32 teams in an array...

$sql = "SELECT
h.nickname AS home,
a.nickname AS away,
h.teamid AS homeid,
a.teamid AS awayid,
s.weekno
FROM schedule s
INNER JOIN teams h ON s.homeid = h.teamid
LEFT JOIN teams a ON s.awayid = a.teamid
WHERE s.seasonno =2014";
$schedule= mysqli_query($connection, $sql);
if (!$schedule) {
die("Database query failed: " . mysqli_error($connection));
} else { 
// Placeholder for data
$data = array();
while($row = mysqli_fetch_assoc($schedule)) {
if ($row['away'] == "") {$row['away']="BYE";}
$data[$row['homeid']][$row['weekno']] = $row['away'];
$data[$row['awayid']][$row['weekno']] = '@ '.$row['home'];
}
}

However, I only want to get info for one specific team, which is stored in the $teamid variable. This should be very easy, right? I have tried multiple things, including this one below (where I added an AND statement of "AND (h.teamid=$teamid OR a.teamid=$teamid)"), but this one still outputs too much...

$sql = "SELECT
h.nickname AS home,
a.nickname AS away,
h.teamid AS homeid,
a.teamid AS awayid,
s.weekno
FROM schedule s
INNER JOIN teams h ON s.homeid = h.teamid
LEFT JOIN teams a ON s.awayid = a.teamid
WHERE s.seasonno =2014
AND (h.teamid=$teamid OR a.teamid=$teamid)";
$schedule= mysqli_query($connection, $sql);
if (!$schedule) {
die("Database query failed: " . mysqli_error($connection));
} else { 
// Placeholder for data
$data = array();
while($row = mysqli_fetch_assoc($schedule)) {
if ($row['away'] == "") {$row['away']="BYE";}
$data[$row['homeid']][$row['weekno']] = $row['away'];
$data[$row['awayid']][$row['weekno']] = '@ '.$row['home'];
}
}

Below is the array that the above outputs. In a nutshell, all I want is that 1st array ([1]) which has, in this example, the Eagles full schedule. It's not giving me too much else and I guess I could live with it and just ignore the other stuff, but I'd rather be as efficient as possible and only get what I need...

Hi all,

Can anyone tell me why the declaration below won't work???

Thnx Ryflex


$amount = array(0 => $_POST['$n[0]'], 1 => $_POST['$n[1]'], 2 => $_POST['$n[2]'], 3 => $_POST['$n[3]']);

I seem to be having a problem with this code. It's supposed to parse the file info.txt and explode comma separated values into an array and then add each value from that file to the end of a URL and POST that url. What I'm getting now is just the first number in the array.
Anyway, here's the code:

Code: [Select]
<?php
$FileName = "info.txt";
$FileHandle = fopen($FileName,"r");
$FileContent = fread ($FileHandle,filesize ($FileName));
fclose($FileHandle);
 
// You can replace the \t with whichever delimiting character you are using
$SplitContent = explode("\t", $FileContent);
 
foreach($SplitContent as $CurrValue)
{

header('Location: http://website.com/file.php?value=' . $CurrValue);

}
?>

I have a dynamic form that I am writing a script for to allow people to modify the fields of the form. I am taking all of the information that they have entered into the post array.

Where I am having a problem is that it is not showing all of the fields in the post array. One of the fields is an image field and the name of the image does not show up in the array when I do print_r or anything.

One other thing that I would like to know is how to get rid of the submit key and value from the array. I have tried using the unset method but it still shows up in the array.

Code: [Select]
<?php

session_start();
include ('includes/connection.php');
connect();

$table = $_GET['table'];
$id = $_GET['id'];

Hi - I have an HTML form which is dynamically produced using CodeIgniter / PHP and presents products a customer has ordered.  When the customer has finished changing his quantities they must now submit the form.  My problem is that my form will contain many of the same named fields for example, 'Product ID', or 'Product Name' or 'quantity'. So now when it gets processed a typical post array like product id could look like this:

Code: [Select]
Array ( [0] => 28 [1] => 24 [2] => 101 [3] => 23 [4] => 17 )
Of course I get an error:

Quote

Severity: Notice

Message: Array to string conversion

Filename: mysql/mysql_driver.php


I really need some advice on how I should pre-process the various POST arrays so I can get them into my DB.

A very grateful student of PHP !

Thanks
