hi...
has anybody seen a reasonably good/basic breadcrumb app that works... new
pages are displayed to the user based upon the user's menu selection...
i'd like to be able to provide a trail at the top of the page, kind of
like..
home -> food -> fruit -> squash
were the user could then select one of the links of the trail, which would
take the user to the earlier page...
searching google results in hundreds of results, but i'm not sure which
examples are good/poor!!
thanks
-bruce

The best approach i've seen untill now is to keep a stack with pages
that have been visited. And each time another script is expected to be
loaded/unloaded the calling script would have to call scriptNext or
scriptPrevious to keep the stack up to date. This way you do not only
have an easy way to build a path with breadcrumbs but also a way to
handle things like ppl that hit the back button after posting a form...

I gave it my best, I could not figure out how to do it in a single
regex. You could make this code more efficient but I think this might
do what you want.
<?
$dico = array(
"abaisser" => "def.php?id=9",
"singer" => "def.php?id=9"
);
$texte = "Abaisser Vous abaisserez la pate, abaisser.Singer Abaisser
Vous abaisserez la pate,<a href=\"some_page.php\">
abaisser.Singer</a>singer<a href=\"some_page_other.php\">
abaisser.Singer</a>";
echo $texte."<br />\n";
preg_match_all('/<a\s+.*?href=[\"\'\s]?.*?>.*?<\/a>/i', $texte, $matches);
if (is_array($matches[0])) {
$counter = 0;
foreach ($matches[0] as $value){
$texte = str_replace ( $value, " REPLACEME$counter ", $texte);
$counter++;
}
}
foreach ($dico as $mot => $def) {
$pattern = '/('.$mot.'\b)/i';
print "$pattern<br />\n";
$texte = preg_replace($pattern,"<a href=\"$def\">$1</a>",$texte);
}
if (is_array($matches[0])) {
$counter = 0;
foreach ($matches[0] as $value){
$texte = str_replace ( " REPLACEME$counter ", $value, $texte);
$counter++;
}
}
echo $texte;

I just tried this code:
$searchenquiry = "Never cry Wolfe";
$mydata = "... Never Cry Wolfe ...";
$new = preg_replace ('/('.$searchenquiry.')/i' , "<b>$1</b>", $mydata);
echo "<td>$new </td>";
here was my output:
<td>... <b>Never Cry Wolfe</b> ... </td>
isnt that what you want?

Hmm? Yes. But it doesn't work for me? It cannot be a php verison thing, can it?
I have phpversion() 4.1.2. I don't get it? :)
Compare with:
http://compcanlit.usherbrooke.ca/new1/db/index.php?searchenquiry=Never%20Cry%20Wolfe
and then:
http://compcanlit.usherbrooke.ca/new1/db/index.php?searchenquiry=Never%20cry%20Wolfe
Here is my code:
<td>".preg_replace ('/('.$searchenquiry.')/i' , "<b>$1</b>", $mydata->AU)." </td>
<td>".preg_replace ('/('.$searchenquiry.')/i' , "<b>$1</b>", $mydata->ST)." </td>
<td>".preg_replace ('/('.$searchenquiry.')/i' , "<b>$1</b>", $mydata->BT)." </td>
<td>".preg_replace ('/('.$searchenquiry.')/i' , "<b>$1</b>", $mydata->JR)." </td>

I don't see anything in the manual that says it can't?

Sorry. I have it working. My fault. I had a previous line:
$mydata->ST = eregi_replace($searchenquiry, "<b>".$searchenquiry."</b>", $mydata->ST);
THANKS!

Greetings all, I have a real simple function. I works well on JPG
images but ImageCopyResized(), or ImagePNG() doesn't seem to be
working. When I view the uploaded file it is still it's original size.
Here is the function. I hope someone can help me, I'm pretty stumped.
function transform_to_profile_pic()
{
$path = $this->origpath;
$type = $this->type;
# make jpg or png image
$img_dst = imagecreatetruecolor(PROFILE_IMAGE_W,PROFILE_IMAGE_H);
if($type == 2)
$img_src = imagecreatefromjpeg($path);
else if($type == 3)
$img_src = imagecreatefrompng($path);
# Overwrite the original with the resized image to the filesystem
imagecopyresized($img_dst, $img_src, 0, 0, 0, 0, PROFILE_IMAGE_W,
PROFILE_IMAGE_H, imagesx($img_src), imagesy($img_src)
if($type == 2)
imagejpeg($img_dst, $path, 100);
else if($type == 3)
imagepng($img_dst, $path . ".png", 100);
}

Several points:
1) Is this copy and paste? You seem to have a missing semi-colon in your code.
2) You do realise you're using a different filename for your resized PNG?
3) Strip your code down to the bare minimum so that you can isolate the
problem and make debugging easier. In this case remove the jpeg stuff and
hence the IF clauses.

I'm going to create a search page that accepts input similar to places like
Yahoo and Google. Example input would be:
Keyword AND keyword2
Keyword -keyword2 +keyword3
"keyword keyword2" -keyword3
Rather than reinvent things though, I'm wondering if anyone here happens to
have a script or function that will handle that type of input. It would be
great if someone already has a function that accepts the initial query, a
table to query against, and a list of fields to query against, and returns
the appropirate SQL statement. Also, I've heard that MySQL's indexing can
support some of this, but I'm not sure how much.
Thanks in advance for any pointers or info you might have on this.

Using a FULLTEXT index and searching in BOOLEAN mode supports the type
of search strings that you wrote.
Consult thine manual!! (The MySQL one) ;)

It doesn't support AND or OR but it does use - + * and others.
>Consult thine manual!! (The MySQL one) ;)
http://dev.mysql.com/doc/mysql/en/Fulltext_Search.html
The problem is getting a FULLTEXT to sort by relevancy. This was a real pain, until
our friend John W. showed me the error of my ways; (see below).
MySQL> "The preceding example is a basic illustration showing how to use the MATCH()
function
MySQL> where rows are returned in order of decreasing relevance"
I never did believe the "examples" helped me:
http://dev.mysql.com/doc/mysql/en/Fulltext_Search.html
You will need something like this to make the operators display according to
relevancy. This works:
SELECT *,MATCH (field1,field2,field3) AGAINST ('Margaret Atwood' IN BOOLEAN MODE)
AS relevancy FROM
mytable WHERE MATCH (field1,field2,field3) AGAINST ('Margaret Atwood' IN BOOLEAN
MODE) ORDER BY
relevancy DESC;
This does not sort by relevancy well at all:
SELECT * (field1,field2,field3) FROM mytable AGAINST ('Margaret Atwood' IN BOOLEAN
MODE);
P.S. John W.: thanks for helping me on my post last week. I finally got this working.

I have been using Zentrifugal.com for quite some time and it works great for
me. They are quite inexpensive too - only $99 per year. I have no
affiliation with them, just a satisfied customer.

Hi,
Can someone help me write a short code snippet to format a string to add:
http://www <http://www/> -- if the string is "google.com" and doesn't have
http://www <http://www/> in front of it
http:// <http://www/> -- if the string is "www.google.com" and doesn't
have http:// in front of it
.if you know of a better way to securely check/format a url like this please
let me know.
Thanks,
Ryan
--- End Message ---
--- Begin Message ---
Ryan,
You can use the following function:
function FormatUrl($url)
{
if (eregi("www", $url))
$result = "http://$url";;
else
$result = "http://www.$url";;
return $result;
}
You can test it using:
$test1 = FormatUrl("google.com");
$test2 = FormatUrl("www.google.com");
print "test1 = $test1<br>";
print "test2 = $test2<br>";
And this will give you the results:
test1 = http://www.google.com
test2 = http://www.google.com
Good luck!

Hi Frank,
Thanks, you got me started. I modified your function a bit. I'm testing for
3 cases now and the appearance of http://, https://, or ftp:// in front of
the string. Let me know if you advise any changes.
<?php
function FormatUrl($url)
{
$url = trim($url);
if (eregi("^(((http)|(https)|(ftp)){1}://)", $url)) {
$result = "$url"; // do nothing
} else if (eregi("^www\.{1}", $url)) {
$result = "http://$url";;
} else {
$result = "http://www.$url";;
}
return $result;
}
?>
