PHP - Remove Comma Before Adding

The web application should allow the user to view the items in a catalogue, add items to a shopping cart, remove items from the shopping cart, and to view the contents of the shopping cart.

Hey guys.
Right ill try explain as best i can.
Basicly we were told to write a php script that can view a shopping cart.

The items in the catalogue should be stored as an array of objects. (The next assignment will require you to store this list of objects in a database). There should also be pages to allow the user to add, edit and delete items in the catalogue.

Thats taken from a brief.Ive spent the most of the week getting it to view a catalog and now it can add items.view the cart its added them to and remove them from the cart and return.
What im having trouble with is making the add function for the the other users or admin* to add/edit/delete.i reckoned adding and deleting wouldnt be so bad considering ive alrready done so.But im kinda stumped on how to do it.i think what the brief wanted was a seprate product add that would actully let u add another product to the cart list on the same page and then u can add that to the shopping basket etc.

Yea real stumped.if only it was through sql it would be so much handier.
ill post the code below.if anyone can help at all in the slightest id be so grateful.Thank you.

Lets say I pull a value from a database field that has a value of 1,2 and what I want to do is seperate them and then run each of those values against a separate table how would that be accomplished.

Hello Guys,

I am trying to strip the last comma but I can't get it to work... Please advise

Here is my code, it adds the coma in between all numbers and on the end.

Code: [Select]
$query1 = mysql_query("SELECT b_id FROM benefits");
while ($row = mysql_fetch_array($query1)) {
$b_id = $row['b_id'];

$b_id . ",";

     echo $b_id2;

}

displays 1,2,3,4,5,6,7,8,9,10,


I also tried this but it didn't work. It removed all the commas

Code: [Select]

$query1 = mysql_query("SELECT b_id FROM benefits");
while ($row = mysql_fetch_array($query1)) {
$b_id = $row['b_id'];


$b_id . ",";
$b_id2 = rtrim($b_id,',');
     echo $b_id2;


}

Hi,
If I need to put commas within a variable how can this be achieved?

i.e. if statement..... {
$output = "text1,text2,text3";

Incase your wondering what I'm trying to do.. basically im using a header file on my site... i want different keywords within the meta tags depending on the page the user is on, so i want to include aprox 20 keywords in the $output which will be inserted in the comma area of the meta tags.


Probably quite an easy way to do it but I'm not sure how to do it! Any help appreciated!

This seems like such a simple error, however I've no idea why I am getting it.

apparently I have an unexpected comma on line 4 of the code below.  I can't work out what the error is.

Any ideas?  Sorry to be a pain if it really is something simple, but I'm a bit new to all this php stuff.

<?php
function percentCalc($value1,$value2,$value3,$value4,$value5,$total)
{
$array=($value1,$value2,$value3,$value4,$value5);
while (list($key,$arraycontent)= each($array))
{
$c_percent=(($arraycontent/$total)*100);
$final_array[]=$c_percent;
}

return $final_array;
}
?>

This is going to sound like a very beginner question, because it is. I am modifying some free code snippets to fit my use and stuck. It's probably a simple fix.

First here is the code. This is printing from a while loop.
<?php print("[". $current_month .",". number_format($remaining_balance, "2", ".", ",") . "],");?>

Here is the last remaining items from the loop at it comes to an end:
[343,14,495.86], [344,13,682.26], [345,12,863.91], [346,12,040.79], [347,11,212.87], [348,10,380.12], [349,9,542.52], [350,8,700.02], [351,7,852.61], [352,7,000.26], [353,6,142.94], [354,5,280.62], [355,4,413.26], [356,3,540.85], [357,2,663.34], [358,1,780.72], [359,892.95], [360,0.00], 

My question is kind of simple, how do I get it do the comma doesn't print on the last print? I need it to end like this: [359,892.95], [360,0.00]

Does that make sense? I don't know if I explained it well. I could really use some help! Thanks so much!

Hi,

I have in column "keywords" comma separated keywords in one row/news. Example in ID "1" in column "keywords" have: "Šport, Fudbal, Četvrta Liga". I want to make a tag-s from those words to be like: http://site.com/tag/sport,  http://site.com/tag/fudbal, http://site.com/tag/cetvrta-liga.

At first I separate those words by:

$input = $vest_keywords;
$removed_spaces = preg_replace('/\s*,\s*/', ',', $input);
$output = explode(',', $removed_spaces);
foreach($output as $tags) {
  echo $tags;
}

This give me: Šport | Fudbal | Četvrta liga

 

But I have a "slug-maker", and I have a problem with redeclare.

/* SLUG */
$string = $output;

Can You help how can I get the links that You se above?

Thanks in advanced!

Code: [Select]
30|24|17,5|4|20,15|13|33,15|22|33,9|20|22
Let's say my output is that,

Realistically every 3numbers is 1 Ticket they are seperated by a "," (comma)

I want to wrap parenthesis around them so the output would look like this

Code: [Select]
(30|24|17) (5|4|20) (15|13|33) (15|22|33) (9|20|22)
Now would I have to use regex.. or not cuz regex is extremely difficult

Thanks

After a lot of lurking, thanks for all the great topics I now have a guestion where I could really use your help.

I am parsing some xml data with the following php:

Code: [Select]
<?php
$data = file_get_contents("XML URL");
$actors = preg_match_all("/<actors>(.+)<\/actors>/", $data, $match);
foreach ($match[1] as $actors)
{
echo $actors; 
} ?>
For the following XML part:

<actors>
<actor id="1234">Actor #1</actor>
<actor id="12345">Actor #2</actor>
<actor id="123456">Actor #3</actor>
</actors>

This gives the ouput: Actor #1 Actor #2 Actor #3

Now I would like to separate the actor names by comma, like this: Actor #1, Actor #2, Actor #3

Does anybody know how to modify the php code for this? Thanks 

How can I replace the comma from a string like this:

You, like this => You like this
You, Derp, like this => You and Derp like this
You, Derp, Derpina, like this => You, Derp and Derpina like this
You, Derp, Derpina, Derpson, like this => You, Derp, Derpina and Derpison like this

Sometimes my 3 column .csv file has commas within quotes:
fruit , cherry , red
vegetables , "celery, carrots" , green
flowers , rose , fresh

When I use this code, I need the data count to stay the same "3" for each row:

while (($data = fgetcsv($handle,2000,',')) !== FALSE) {
print count($data); // prints "3" ... then prints "4" .... then prints "3"
}

How do I get fgetcsv to see that "celery, carrots" is just one unit of data?

Thank you.

Hello Guys,

I check the price field on the server side and I am trying to figure out how to allow a comma in the price field

example 2,300

Code: [Select]
function check_Price($price,$member_id,$description,$ip){
if (isset($price) && (!is_numeric($price)))
{
      do something here
}

}
Thanks in Advance!

Hi everyone,

Basically i have a little task to do and was wondering if anyone is able to help, i would very grateful

First task is for me to read a comma delimted file into PHP and store everything into an Array:

Comma Delimited File = "houses.txt" (As a reference it means, PostCode, Price ('000's), picture and houses visits)
HA11QS, 200, house1.jpg, 4
HA22BR, 280, house2.jpg, 10
HA33AB, 390, house3.jpg, 3
HA44CD, 320, house4.jpg, 8

my basic php for now is:
Code: [Select]
<?php

function getHouse ()
{
$filename = "houses.txt";
$fileRead   = fopen($filename, "r");

$rowsArr  = file ($filename);
for ($i=0; $i < count($rowsArr); $i++)
{
$lineDetails = $rowsArr[$i];
print  $lineDetails . "<br>" ;
}

fclose($fileRead);
}
?>

<h3> Welcome </h3>

<p> PostCode Number Picture Visits </p>

<?php

echo getHouse();

?>

What i need to do next is to have a static web form where a user can input a maximum price e.g. 300
And that will return all the houses which are under 300 by reading the whole array

I have a basic form setup:

Code: [Select]
<form method="post" action="maxtest.php" >
<input type="text" name="userprice" value="" />

<input type="submit" name="button" value="Submit" />
</form>
and also i have a an idea that i need something along the lines of:
Code: [Select]
$userValue = $_POST['userprice'];

if ($userValue == 300)

{
}

Im a bit stuck on how to incorporate the comma delimted array

Please help me, thank you
