problems with implode()

[DeepBlerg]

Hi,

I have a form on a page that has 5 text fields (tfield0, tfield1, tfield2 etc etc) which once the form is processed, it creates an array with the 5 values from the text fields and puts into database.

Here's some of the code:

$thedata = array();
$tcount = 5
$i = 0;
while ($tcount != 0) {
$thedata[] = $tfield[$i];
$i++;
$tcount--;
}
$thevar = implode(&quot;<sp>&quot;, $thedata);

For example, the values in the 5 text boxes where a,b,c,d,e. Then I would expect $thevar to equal &quot;a<sp>b<sp>c<sp>d<sp>e&quot;

But it is blank. What am I doing wrong?

Thanks in advance.

There's nothing wrong. I just checked it and it works without a glitch. Here's the codefragment I used to test it:

<?php

$tfield = array('a', 'b', 'c', 'd', 'e');

$thedata = array();
$tcount = 5;
$i = 0;
while ($tcount != 0) {
$thedata[] = $tfield[$i];
$i++;
$tcount--;
}

$thevar = implode(&quot;<sp>&quot;, $thedata);

echo $thevar;

?>

The echo shows &quot;abcde&quot; and by doing a view-source you can see that the HTML-code contains &quot;a<sp>b<sp>c<sp>d<sp>e&quot; It's not a lie if YOU believe it ;-)

Hmm, by looking closer at your post it see that you're using $tfield to read the values but your variables are called $tfield0, $tfield1, etc right? So you're not accessing those variables at all, that's why you get an empty result. It's not a lie if YOU believe it ;-)

The dr. is right. You also seem to have the arguments reversed in the implode call. Try:

$thedata = array();
$i = 0;
while ($i < 5) {
$varname = 'tfield'.$i++;
array_push($thedata,$$varname);
}

$thevar = implode($thedata,'<sp>');
