can any one sujjest me something....

Good to see you have written some code.

Try turning on the error hanlding and telling what you see on the page when you run it. This will shed some light on what is happening.

Also when yo say 'there is some error' what do you mean? What are you currently seeing, what do you think is happening.

My old university tutor would have sent me packing if I'd said 'there's some error please help.' You have to define the problem a bit more, especially as we cannot see your system/setup completely but just the code you post (thanks for posting it).

Let us know what comes back from your next set of tests.

oh ok....its not showning anything in the form jst form text box is appearing and then within it it appears
for($i=0;$i <= $lcount ;$i++){ type=text > } lke this in html page

**gregerly** · Jul 31 '07, 06:56 AM

First thing that jumps out at me is that you have PHP code not inside PHP tags:

[HTML]<FORM METHOD=post ACTION="test1.p hp">
for($i=0;$i <= $lcount ;$i++){
<input name= <?php $name[$i] ?> type=text > <?php $value[$i] ?>

}
<INPUT TYPE=SUBMIT>
</form>[/HTML]

which should be:

[HTML]<FORM METHOD=post ACTION="test1.p hp">[/HTML]
[PHP]<?
for($i=0;$i <= $lcount ;$i++){
<input name= <?php $name[$i] ?> type=text > <?php $value[$i] ?>

}
?>[/PHP]
[HTML]<INPUT TYPE=SUBMIT>
</form>[/HTML]

i tried wht u told but not working
error:type=text > } ?>

**nathj** · Jul 31 '07, 07:22 AM

Hi,

Try changing this section

[PHP]
<?
for($i=0;$i <= $lcount ;$i++){
<input name= <?php $name[$i] ?> type=text > <?php $value[$i] ?>

}
?>

[/PHP]

To something more like this:
[PHP]
<?php
for ($i=0; $i <= $lcount; $i++)
{
echo '<input type="text" name=' . $name[$i] . 'value=' . $value[$i] . ' />' ;
}

?>
[/PHP]
The first sample has nested php tags, I don't know if this is a problem or not but it sure looks weird. Also the raw HTML inside the php tags is a potential problem.
The second sample removes the need for this and should work just fine, assuming that the two arrays are correct.

So, your final page could look like this (all in php):
[PHP]
<?php
echo '<form name = "testform" method="post" action="test1.p hp">
';
for ($i=0; $i <= $lcount; $i++)
{
echo '<input type="text" name=' . $name[$i] . 'value=' . $value[$i] . ' />' ;
}
echo '<input type="submit" value="Complete "/>';
echo '</form>';
?>
[/PHP]

Have a play with this and let us know what you get.

<?php
$file=fopen("/var/lib/penguin/Desktop/welcome.txt","r ")or exit("Unable to open file!");
$x=0;
for($i=0 ; $i != feof($file) ; $i++)
{
$data = fgets($file,$x) ;
$str = explode(':', $data);
$name[$i] = $str[0]; // piece1
$value[$i] = $str[1]; // piece2

$i = $i + 1;
}

echo '<input type="submit" value="Complete "/>';

echo '</form>';

?>

</form>
</body>
</html>

this is wht i hve used as code..but still not working...

error:'; for ($i=0; $i <= $lcount; $i++) { echo '' ; $i = $i + 1; } echo ''; echo ''; ?>

i thnk there is a problem in 2 arrays...is th 1st php code proper

**nathj** · Jul 31 '07, 07:58 AM

What information is in the two arrays you have? It may be that we need to adjust the code to include quote marks if the data in the array contains spaces.

Also are you getting an error message - what is the message exactly?

the file contains
name:pradeep
palce:blore

i am taking the 1st line into data and then using explode so as 2 split into 2 arrays say name and pradeep..and storing them in name[$i] and value[$i]
then i am moving to next line wit help of $x+1024 and then splitting the 2nd line also..
then using the variables in the html form..
there is no proper error ..but its displaying jst tht wht i said in last msg.

explode() will generate one array:
[PHP]
<?php
$lcFileContent = file(_FileName_ );
$laTest = explode(":", $lcFileContent) ;
print_r($laTest );
[/PHP]

This single array will then contain 'name' and 'pradeep'. The code abpve will print the array and you will be able to see what is in it and how best to manipulate.

but this is wht in found i php manual

If you want to split a price (float) into pounds and pence.

or dollors and cents etc etc.

$price = "6.20";

$split = explode(".", $price);
$pound = $split[0]; // piece1
$pence = $split[1]; // piece2

echo "&pound $pound . $pence\n";

seeing this only i used tht...

hey i am not finding a way wht to do..if i dont show the code before SATURDAY i wll kicked off frm the job..,

First of all please use CODE tags, it makes reading your post much easier!

Second, you may be in a panic but I'm just trying to help and perhaps you need to take a breather before reading this and come back to it with a clearer mind. I know I need to do that sometimes.

The code sample you posted
[PHP]
$price = "6.20";

$split = explode(".", $price);
$pound = $split[0]; // piece1 - "6"
$pence = $split[1]; // piece2 - "20"

echo "&pound $pound . $pence\n";
[/PHP]
Simply takes string and splits on the occurrence of '.' into one array called $split. This array has numeric keys, starting at 0 and can be referenced accoridingly.

In your case all that is different is the source of the original string - you want it to come from a file.

What you need to do, is what you were doing earlier (I showed the file() function and print_r() to help you understand what happens with the xplode function).

Open the file and loop through one line at a time.
For each line create a variable of the line.
Explode the variableit into an array
Loop through this array (this is now a nested loop)
This array will, according to your data structure, contain a pair of values, do what you want with these. Note; as its a numeric array it is simple to loop with a for loop based on the count() of the array - remember arrasy start counting at 0.

This is the psuedo code for you. Just write it up. I've given enough help now on this. I do have a job to do myself you know, with my own deadlines to meet - you're not the only one under pressure.

If you write the code, as outlined, and need some help post it back here with lots of information and use the CODE or PHP tags to format it.

pradeepjain,

Please read the Forum rules and Posting guidelines while you using the forums.And please pay your kind attention to these;

Please use a Good thread Title next time.
Please wrap your coding with code tags
Using all caps for posting threads/posts is equal to shouting to the others.so DO NOT USE IT ALWAYS. just use it for Highlighting purpose. as i did. :)

So thats it.Thanks

I HVE TRIED THIS IS THIS WHT U SAID TO DO

[PHP]<?php
$file=fopen("/var/lib/penguin/Desktop/welcome.txt","r ")or exit("Unable to open file!");
$x=0;
for($i=0 ; $i != feof($file) ; $i++)
{
$data = fgets($file,$x) ;
$str = explode(':', $data);
print_r($str);
for($j = 0; $j < count($str); $j++){
echo "str #$j = $str[$j]<br />";
}
$x=$x+1024;
}
$lcount=$i;
?>
