The following code should get a query (addressed to amazon ads) to get a link with author only if author is not AA.VV. (in Italian → autori vari = several [various] authors). Otherwise it should search only for the title (in Amazon “AA.VV.” doesn’t work)
if(($trad_titolo != '') and ($autore != 'AA.VV.')) {echo ", tr.it. <i>$row[trad_titolo]</i>, $row[trad_edizione], $row[trad_luogo] $row[trad_data] (<a rel=\"external\" href=\"$myamzcode1=$amztitolotrad$myamzcode2";}
else {echo ", tr.it. <i>$row[trad_titolo]</i>, $row[trad_edizione], $row[trad_luogo] $row[trad_data] (<a rel=\"external\" $myamzcode1=$amztitolotradAAVV$myamzcode2";}
//originale in italiano
if(($trad_titolo = '') and ($autore != 'AA.VV.')) {echo "(<a rel=\"external\" href=\"$myamzcode1=$amztitolo$myamzcode2";}
else {echo "(<a rel=\"external\" href=\"$myamzcode1=$amztitoloAAVV$myamzcode2";}
However I get a webpage with
two (identical) links to amazon
both with the title ($trad_titolo) and both without author ($autore)
You can see the output php source code of webpage
`
AA.VV. , Martin Lutero , Milano 1985, tr.it. , , ( ( .
Roland Herbert Bainton , Here I Stand: A Life of Martin Luther , Nashville 1950, tr.it. Lutero , Einaudi, Torino 1960 ( ( . `
Where I’m wrong?
EDIT
Why the following code doesn’t work as expected?
if(($trad_titolo != '') and ($autore != 'AA.VV.')) {echo ", tr.it. <i>$row[trad_titolo]</i>, $row[trad_edizione], $row[trad_luogo] $row[trad_data] (<a rel=\"external\" href=\"$myamzcode1=$amztitolotrad$myamzcode2";}
else {echo ", tr.it. <i>$row[trad_titolo]</i>, $row[trad_edizione], $row[trad_luogo] $row[trad_data] (<a rel=\"external\" $myamzcode1=$amztitolotradAAVV$myamzcode2";}
//originale in italiano
if(($trad_titolo = '') and ($autore != 'AA.VV.')) {echo "(<a rel=\"external\" href=\"$myamzcode1=$amztitolo$myamzcode2";}
else {echo "(<a rel=\"external\" href=\"$myamzcode1=$amztitoloAAVV$myamzcode2";}

($trad_titolo = '')
Look verrry carefully here…

=
(assignment) vs ==
(comparison).

Thank you. I tried with: ($trad_titolo = ='')
, but unsuccessfully …
Define ‘unsuccessfully’.
Your code will spit out two links in all codepaths.

Yes: two links, while I need only one, the Italian one.
So why have you got two if’s?

Well I cant answer for you why you have two ifs. You put them into the code, why did you put them there if you only want one?

Ah, sorry. I didn’t understand: you did mean two“if".
I did several attempts…
Well, each of those will generate a link. So… keep the one you need to keep?

Indeed. It seems that this code works
if(($trad_titolo != '') and ($autore != 'AA.VV.')) {echo ", tr.it. <i>$row[trad_titolo]</i>, $row[trad_edizione], $row[trad_luogo] $row[trad_data] (<a rel=\"external\" href=\"$myamzcode1=$amztitolotrad$myamzcode2";}
else if (($trad_titolo != '') and ($autore == 'AA.VV.')) {echo ", tr.it. <i>$row[trad_titolo]</i>, $row[trad_edizione], $row[trad_luogo] $row[trad_data] (<a rel=\"external\" $myamzcode1=$amztitolotradAAVV$myamzcode2";}
//originale in italiano
else if(($trad_titolo == '') and ($autore != 'AA.VV.')) {echo "(<a rel=\"external\" href=\"$myamzcode1=$amztitolo$myamzcode2";}
else {echo "(<a rel=\"external\" href=\"$myamzcode1=$amztitoloAAVV$myamzcode2";}
Now I have lo leave, but after I will check again.
Thank you so much!
EDIT
Yes, it works!
Thank you very much!
I have not done much PHP but I doubt that = =
is the same as ==
. My guess is that = =
is the same as =
(2 assignments would be the same as 1). Also if there is no space in =''
(no space between the equal sign and the quote) then that would likely be a problem too.
The space between the equals gives an “unexpected token” error.
It needs to be ==
and not = =
for comparison.
