Pass Variable in link

[JRockfl]

How can I pass the id field from my query?
details.php?id=

// create array $row holding all the results from your query
while($row = mysql_fetch_array($result)) {

// display results

echo $row["snippet"] . "<br>\n";

Also what is that perod for after the ] ?

The period combines strings of words into a single string.
To show how the period works, all the following are equivalent: -

print "this is a " . "<b>" . "great place</b>";
print "this is a <b>great place</b>";
print "this is a <b>" . "great place</b>";

while($row = mysql_fetch_array($result)) { 
   echo "<a href='details.php?id=" . $row["id"] . "'>Product</a>\n";

}

Obviously where it says Product, you would replace that with the name of whatever it is you're pulling out of your database. That will create a link that goes to details.php and passes the variable id in the url with the value pulled from the database for that particular record.

adding a variable that is pre defined

for example
a button contains the action

                              "show_cart.php?new=$isbn" 

then the isbn is in the $new variable on the show_cart page.

The dot is an operator that adds what follows to what preceeds.

for examle:
$a .= $b this equlas $a = $a . $b

John.adams=johnadams

it's used to join strings or other data together.

*note: it's not addition

Does this help?

perfect!

how can i replace the word product with one of my variables instead?

<!-- #id# and #product# are variables from the query. I typed it in CF...but thats what I want to kinda do with PHP -->

<a href="details.cfm?id=#id#">#product#</a>

[cgraz]

echo "<a href='details.php?id=" . $row["id"] . "'>" . $row["field_name_in_db"] . "</a>\n";

Replace field_name_in_db with the field name in your database that you want to display there.
