I have inherited a piece of code from a client which I cannot get to work properly. The validation in the script doesn’t work – ( i.e. when a user doesn’t put anything into a search box they receive this error. ( users can search via town or postcode )
Code: Select all
“Warning: stristr() [function.stristr]: Empty delimiter. in /home/ public_html/newsite/export.php on line 19”Code: Select all
<?
$searchterm=$_GET[search];
$fname="export.csv";
$numfields=7;
$fd = fopen ($fname, "r");
$contents = fread ($fd, filesize ($fname));
$contents=trim($contents);
echo "<br><br>";
$contents=strtr($contents,chr(10),",");
fclose ($fd);
$fvalues=explode(",",$contents);
$numbers=count($fvalues);
$found=0;
for ($i=0;$i<=$numbers;$i=$i+$numfields)
{
$a1=$fvalues[$i+2];
if (stristr($a1,$searchterm))
{
$company=trim($fvalues[$i]);
echo "<p><b>$company</b><br>";
$a1=$fvalues[$i+1];
echo "Contact: $a1<br>";
$a1=$fvalues[$i+2];
echo "Address: $a1<br>";
$a1=$fvalues[$i+3];
echo "Telephone: $a1<br>";
$a1=$fvalues[$i+4];
echo "Fax: $a1<br>";
$a1=$fvalues[$i+5];
echo "Email: <A HREF='mailto:$a1'>$a1</A><br>";
$a1=$fvalues[$i+6];
// echo "Website: $a1</A><br>";
if ($a1=="None")
{
$a1="";
}
echo "Website: <A HREF='http://$a1' TARGET='_blank'>$a1</A><br>";
$found=$found+1;
echo"<br></p><hr>";
}
}
if ($found>0)
{
echo "<p><br>$found member(s) found.<br></p>";
}
else
{
echo "<p><br>Sorry, no members found in that area.<br></p>";
}
?>I have a very little knowledge of PHP and would really appreciate any guidance or help that you could share. Thanks.
