setting several selects to a specific position

[jaco]

Hi guys, thank for any help. This does not appear like a difficult problem but it has me stymied. I have several selects, the 1st item of each is "--Specify--" so that the user has to specifically choose an item. Once an item is selected on any select the others should be set to the 1st item or "--Specify--" to avoid confusion.

 

If you want to see the complete code it on this web page: http://chordsandguitar.com/progressions-test.php

 

The relevant code is:

 

if ($prog1_menu != "--Specify1--")
{
 $prog2_menu = "--Specify--";
 echo "set prog2 to Specify"; 
 }

if ($prog2_menu != "--Specify2--")
{
 $prog1_menu = "--Specify--";
 echo "set prog1 to Specify"; 
 }

echo "<form action = \"progressions-test.php?s_sort_all=$sort_all&s_prog1_menu=$prog1_menu&s_prog2_menu=$prog2_menu&s_prog1_trigged=$prog1_trigged&s_prog2_trigged=$prog2_trigged\" method = \"GET\">";
//also stores the values of the drop-downs when Select button is pushed so they can be retrieved when the web page is loaded again



echo "                                                 Ascending bass line";
echo "<br />";
echo "Select a progression: <a href=\"http://www.chordsandguitar.com/progressions-test.php?s_sort_all=All&s_prog1_menu=--Select--&s_prog2_menu=--Select--\"\"><big>ALL</big></a>";
echo "     ";

echo "<select name=\"prog1_menu\"  onchange=\"this.form.submit();\">";

echo "<option value=\"--Specify1--\">--Specify--</option>";
if ($prog1_menu == "ii-iii-IV-V progression") echo	"<option SELECTED value=\"ii-iii-IV-V progression\">ii-iii-IV-V progression</option>";
else echo	"<option value=\"ii-iii-IV-V progression\">ii-iii-IV-V progression</option>";
if ($prog1_menu == "I-ii-IV-V progression") echo	"<option SELECTED value=\"I-ii-IV-V progression\">I-ii-IV-V progression</option>";
else echo	"<option value=\"I-ii-IV-V progression\">I-ii-IV-V progression</option>";
if ($prog1_menu == "I-iii-IV-V progression") echo	"<option SELECTED value=\"I-iii-IV-V progression\">I-iii-IV-V progression</option>";
else echo	"<option value=\"I-iii-IV-V progression\">I-iii-IV-V progression</option>";
echo  "</select>";

echo "   ";

echo "<select name=\"prog2_menu\" onchange=\"this.form.submit();\">";

echo "<option value=\"--Specify2--\">--Specify--</option>";
if ($prog2_menu == "I-sharpIo7-ii7-sharpIIo7 progression") echo	"<option SELECTED value=\"I-sharpIo7-ii7-sharpIIo7 progression\">I-#Io7-ii7-#IIo7 progression</option>";
else echo	"<option value=\"I-sharpIo7-ii7-sharpIIo7 progression\">I-#Io7-ii7-#IIo7 progression</option>";
if ($prog2_menu == "I-sharpIo7-ii7-V7 progression") echo	"<option SELECTED value=\"I-sharpIo7-ii7-V7 progression\">I-#Io7-ii7-V7 progression</option>";
else echo	"<option value=\"I-sharpIo7-ii7-V7 progression\">I-#Io7-ii7-V7 progression</option>";
echo  "</select>";

echo "</form>";

 

I am trying to identify which select box has been used so that I can set all the other boxes to the 1st item but I wind up re-setting all the boxes.

 

Cheers,

 

Jacques

I assume you are setting $prog2_menu and $prog1_menu from the GET variables earlier in your PHP code?

 

You really need to learn to use some CSS.  This is UGLY!

echo "                                                 Ascending bass line";

Sorry that's not going to work as both selects are in the same form and POSTED when one is selected.  If you really need two selects, for example major and minor scales, I would suggest you make the first selection with these options major, minor then depending on this selection, show different options in the second selection box.
