Code: Select all
<?php
print("<TR><TD colspan=5><textarea name="editing" cols=60 rows=10 NOWRAP>");
if($edit){
for($n = 0; $n<count($edit); $n++){
$TheFile = "form_data/$edit[$n]";
$Open = fopen ($TheFile, "r+");
if($Open){
$data = file($TheFile);
$getline = explode("\t",$data[$n]);
print("$getline[0]\n$getline[1]");
fclose($Open);
}else{
print("Unable to open a file<BR>\n");
}
}}
print("</TEXTAREA>");
?>
Ok guys why doesnt this read all the lines in the file, have used same one before and has worked but this is inside a textarea although that shouldnt really make much difference, should it?

I don't think it has something to do with textarea.
This should be reading only the $n-th line of each file since you're exploding only the $n-th line. Try implement another for loop to read every line. Something like this:
Code: Select all
<?php
print("<TR><TD colspan=5><textarea name="editing" cols=60 rows=10 NOWRAP>");
if($edit){
for($n = 0; $n<count($edit); $n++){ // could also use a [php_man]foreach[/php_man]
$TheFile = "form_data/$edit[$n]";
$Open = fopen ($TheFile, "r+");
if($Open){
$data = file($TheFile);
for($i = 0; $i<count($edit); $i++){
$getline = explode("\t",$data[$i]);
print("$getline[0]\n$getline[1]");
}
fclose($Open);
}else{
print("Unable to open a file<BR>\n");
}
}
}
print("</TEXTAREA>");
?>

why use fopen() when you aren't using fread/fwrite?
Code: Select all
<?php
print("<TR><TD colspan=5><textarea name="editing" cols=60 rows=10 NOWRAP>");
if($edit){
foreach($edit as $k => $n){ // could also use a foreach
$TheFile = "form_data/$n";
if(is_readable($TheFile)){
$data = file($TheFile);
for($data as $line){
$getline = explode("\t",$line);
print("$getline[0]\n$getline[1]<br />\n");
}
}else{
print("$TheFile isn't readable or doesn't exist.<br />\n");
}
}
}
print("</TEXTAREA>");
?>

Thanks,
