$_post Problems	View Content

I have a code designed to build buildings on space colonies.
The problem is that once you click the form button, the building is built, but you need to reload the page before it will show the updated count.
Is there a way to refresh a page so that the change shows up without the user doing anything?

Code: [Select]
<?php
$dbhost = 'localhost:3306';
$dbuser = 'root';
$dbpass = 'root';
$dbname = 'aosdb';
$conn = mysql_connect($dbhost,$dbuser,$dbpass)
or die ('Error connecting to mysql');
mysql_select_db($dbname);
$query="SELECT * FROM IMPrints";
$result=mysql_query($query);
$name = mysql_result($result, 0, 'name');
$work = mysql_result($result, 0, 'workers');
$effi = mysql_result($result, 0, 'efficiency');
$cost = mysql_result($result, 0, 'cost');
$iron = mysql_result($result, 0, 'iron');
$copp = mysql_result($result, 0, 'copper');
$silv = mysql_result($result, 0, 'silver');
$titan = mysql_result($result, 0, 'titanium');
$gold = mysql_result($result, 0, 'gold');
$uran = mysql_result($result, 0, 'uranium');
$plat = mysql_result($result, 0, 'platinum');
$diam = mysql_result($result, 0, 'diamonds');
$oil = mysql_result($result, 0, 'oil');
$water = mysql_result($result, 0, 'water');
?>
<div class="building">
<p class="bd" id="name">| Name: <?php echo $name ?></p>
<p class="bd" id="workers">| Staff: <?php echo $work ?></p>
<p class="bd" id="efficiency">| Effic: <?php echo $effi ?></p>

Problems With Writing $_post To Xml

Similar Tutorials

View Content

I posted a question on this topic, but didn't receive any replies, but my question has evolved since...

I have a massive form sending post data to a page that I want to write the values to an XML below is an example of an echo that I did in the format of:

E07_37_1 - 1
E07_37_2 - 1

Should be written in the XML, similar to:

<E07_37>Data</E07_37>
<E07_37>Data</E07_37>

Many all of the elements will be embedded in a parent node to one level or another (some of them can get pretty deep) ie:
Code: [Select]
<...>
<E07>
<E07_37_0>
<E07_37>Data</E07_37>
...For this I have a switch statement to determine what parent elements the given element belongs to ie:
        switch ($row){
         ...
        case "E07_03":
        case "E07_04":
        case "E07_09":
        case "E07_10":
        case "E07_14":
            $cursub = $curblk."_03_0";
            $xml->Header->Record->$curblk->$cursub[$multi]->$row = $value;
            break;
I'm writing to the XML like so:
$dom = new DOMDocument('1.0');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($xml->asXML());
file_put_contents('output.xml', $dom->saveXML());

So, I have thought much of that stuff through, and I thought I was on the right track but from what I can tell, the values in $xml aren't updating (from the existing value to the new value) nor new elements aren't being added. The only thing that is changing from the old XML to the new is it's adding a random (and unwanted) element at the end of each <E##> parent block: <E>value of last element in parent structure</E> and some times <0>blah</0>.

So I'm pretty much completely lost now and feel like most of what I've done is a complete waste of time. Someone please help! I'm sorry if my explanation is long and hard to understand but I figured it would be better than posting 300+ lines of code - So instead I attached it...

Any help is greatly appreciated...

Hi guys,

I have a form using radio buttons.
For the radio button, lets just say i have the id name as 'rim' + number eg; rim0, rim1, rim2....

When i post the data to another file to execute the data collected, naturally i would use the:
Code: [Select]
$rim0=$_POST['rim0'];
$rim1=$_POST['rim1'];
....
$rim10=$_POST['rim10'];
i tried to shorten this process using this method:
Code: [Select]
//$q is part of the post variable.
for($x = 0; $x < count($q); $x++){

$rim[]=$_POST['"rim"."$x"'];
}
But i get this error
Code: [Select]
Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20
Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20

Is there something wrong with my POST syntax?

Hi guys, running through this tutorial at the moment:

I seem to keep having problems with the $_POST variable. Is that obsolete syntax now?

Here's the part I get an error on:

<html>
<body>
<?php
$quantity=$_POST['quantity'];
$item=$_POST['item'];

echo "You ordered".$quantity."".$item.".<br/>.";
echo "Thank you for ordering from Boombaby art supppplies!";

?>

Here's the error:

Any help would be appreciated. I tried googling but everything didn't seem to answer my question or was too confusing.

$_post Variables

Similar Tutorials

View Content

Ok- I have seen it go both ways on this forum and I was wondering which is correct- or more secure.

I have a script that receives $_POST variables from a form. Which is better- to change the name of the $_POST variable to do script manipulations or to simple do them with the $_POST['whatever']

$whatever = $_POST['var_from_form'];

or simply utilize $_POST['var_from_form']

I know it would be less typing changing it to $whatever, but does it really matter?

And yes- register_globals is off.

Cheers-

Hi All,

I am having a bit of difficulty with a form I've built that has some PHP elements in it. The issue is it is just not sending the values (which are in hidden fields).

Code is:

Code: [Select]
while($row = mysql_fetch_array($result)){

echo '<tr style="padding: 15px;">';
echo '<td>' . $row['product_id'] . '</td>';
echo '<td>' . $row['name'] . '</td>';
echo '<td>' . $row['catalogue_id'] . '</td>';
?>
<td>
<form method="post" enctype="multipart/form-data" action="<?php echo str_replace( '%7E', '~', $_SERVER['REQUEST_URI']); ?>">

<input type="hidden" name="editform" value="Y">

<input type="hidden" name="prodid" value="<?php echo $row['product_id'] ?>">
<input type="hidden" name="prodname" value="<?php echo $row['name'] ?>">
<input type="hidden" name="catalogue_id" value="<?php echo $row['catalogue_id'] ?>">

<input type="submit" name="Edit" value="<?php _e('Edit', 'pmimp_trdom' ) ?>" />

Would it have something to do with splitting up the php tags?

I have a form with radio buttons, depending on if a person selects yes, they will be given an answer after they hit submit.

I don't want to do a bunch if un-necessary coding, so I'm trying something else, but it's not working.

My form is this
Code: [Select]
<table width="100%" border="0" cellspacing="0" cellpadding="4">
<tr>
<td align="center" valign="top">Yes</td>
<td align="center" valign="top"><input type="radio" name="phone1" id="phone1" value="1" /></td>
<td align="center" valign="top">No</td>
<td align="center" valign="top"><input type="radio" name="phone1" id="phone1" value="2" /></td>
</tr>

</table>

My code is this
Code: [Select]
<?php
  if(isset($_POST['submit'])) {

$key;
$key['phone1'] = "testing phone 1";
$key['phone2'] = "testing phone 2.";

foreach( $_POST as $key => $value) {
if($value == "1"){
echo $key."<br />";
}
}
  }
?>

Now, it does not show the wording associated with $key if the value is 1.

Can anybody help me out here? This form is going to have over 100 questions.

Thanks in advance.

$_post Not Grabbing The Value?

Similar Tutorials

View Content

I think this belongs here, but my $_POST['gender'] won't grab the gender that was submitted through a form.

I am using AJAX so the page doesn't have to reload so it can go in a smooth transition, but the AJAX is grabbing the value perfectly fine.
I have a feeling the $_POST isn't grabbing the value because the page isn't reloading.. but I don't want to reload it.
These codes are all on the same page.

Here is my Javascript:
Code: [Select]
<script>
function chooseGender()
{
var gender = $('input[name=gender]:checked', '#submitgender').val();
if(gender)
{
$.ajax(
{
type: "POST",
url: window.location.pathname,
data: gender,
success: function()
{
alert("You have chosen to be a " + gender); //It's grabbing it perfectly fine!
$("#submitgender").hide(); //It hides the gender table so they can't choose a gender since they already have chosen one.
$("#rest").fadeIn(); //Shows the other table that's labeled "rest" as it's ID so they can choose what base, eyes, etc for that specific gender they've chosen.
}
});
}
else
{
alert('Select a gender.');
}
}

$(function tabs()
{
$( "#tabs" ).tabs();
});
</script>
But here is the PHP inside the #rest table:
Code: [Select]
<?php
$gender = $_POST['gender'];

$sql = "SELECT * FROM habases WHERE gender='".$gender."'";
$result = mysqli_query($cxn, $sql) or die(mysqli_error($cxn));
print_r($sql);
while ($row = mysqli_fetch_assoc($result))
{
$baseimage = $row['image'];
$baseskin = $row['skin'];

echo "<img src=\"http://www.elvonica.com/".$baseimage."\" value=\"".$baseskin."\">";
}
?>
And this is what I'm getting for the print_r:
Quote

SELECT * FROM habases WHERE gender=''

$nav_title=$_POST["nav_create_title"];
$nav_visible=$_POST["nav_visible"];

echo $nav_title;
echo $category_pos;
echo $nav_visible;

As you can see, it prints the correct value and name from the array... why the heck can't I assign or echo it?

Here is how I am sending it from the other page in a form (it used to be simple, but I've been trying every work around i can think of:
<?php
$result=mysql_query("SELECT * FROM category WHERE visible='1' ORDER BY position ASC");
$row=mysql_fetch_array($result);
$positionID=$row['position'];
$position=$row['position'];
$selectname= "Select A Position:<br />";
$selectname .= "<select name=";
$selectname .= "'category_position'";
$selectname .= ">";
echo $selectname;
$rownumber=mysql_num_rows($result);
$rownumber_temp=$rownumber+1;
For($i=1; $i<=$rownumber_temp; $i++)
{
echo "<option value= $i>" . $i . "</option></br>";

}
$selectname2 = "echo \"<br />\"";
$selectname2 .= "echo \"<br />\"";
$selectname2 .= "echo \"</select>";
echo $selectname2;

It generates a image and gets data from the name thats in the url. I am wanting to make a form where they fill out their name and what color they use.

Is it possible to redefine a $_POST after PHP has received the value of it via a HTML form?
Something like this:

Hello, I am quite new to the php and website scene and i am trying to find the best way to validate and sterilize my $_post the way i have come up with is

$id = filter_var(mysql_real_escape_string($_POST['id']),FILTER_SANITIZE_NUMBER_INT);

$id = mysql_real_escape_string($_POST['id']);
$id1 = filter_var($id,FILTER_SANITIZE_NUMBER_INT);

which will be the best way to do it or is there a better way. Thanks

Is It Safe To Use $_post For This?

I have a button that uses $_POST to send information to another page. The data is in a hidden input so it's not possible for users to change information. I have nothing to check if the data is correct on the other page. Is it still possible for people to change the $_POST data though? Or somehow send false $_POST data to the other page?

How come $_POST['email'] isn't getting passed down the steps? I have a hidden field that holds it in each step... what am I overlooking?
