POvalidate drop down list echoed from php to html with javascript?
text
Body
copied!<p>ok so, the title of this question might be a little confusing, and i will try to explain it to you: i have a php file with an array containing multiple form fields like this:</p> <pre><code>$var = array(0 => '<input type=....>', 1=> '<input type=....>'); </code></pre> <p>and i created a while loop to loop through the array to show them in a table, something like this:</p> <pre><code>echo '<table>'; while($row = mysql_fetch_array($result)){ $num = $row['fieldId']; $field = $num.' '.$row['field']; echo '<tr><td>'.$field.'</td>'; echo '<td>'.$var[$q].'</td></tr>'; echo '<tr><td>&nbsp;</td></tr>'; $q++; }; echo '</table>'; </code></pre> <p>i included this php file in a html file so i can get a table with two columns, the first one with $field from the database and the second with $var[$q] which is some input field taken from the $var array. Believe it or not that actually works, now the problem is that inside that $var array i have a <code><select></code> field with multiple options, i want to validate that field with some javascript, but for some reason i can't get the values assigned in <code><option value="SOMEVALUE"></code> . i don't know why but i can't, one thing i found weird is that in that $var array i have some radio buttons which i <strong>CAN</strong> validate with javascript.</p> <p><strong>more info:</strong> the html file that includes the php file has this:</p> <pre><code><html>.... <form name="mainForm"> <?php include 'myPhpFile.php'; ?> <input type="button" name="btnNext" onclick="functionToValidate();"> </form> ...</html> </code></pre> <p>so basically when i include my php file it creates a table and adds fields to it filling them with data from a mysql database and some input fields using the $var array shown above all that works, but the problem is when i click the next button it calls a javascript function to validate the fields, everything works until it gets to the <code><select></code> input, i can validate radio buttons, text fields and textareas but i can't validate those <code><select></code></p> <p>this is the javascript function i am using:</p> <pre><code>function myFunctionNameHere(){ if(!document.mainForm.p1_1[0].checked && !document.mainForm.p1_1[1].checked) alert("1 - some warning here"); else if(!document.mainForm.p1_2[0].checked && !document.mainForm.p1_2[1].checked) alert("2 - some warning here"); else if(!document.mainForm.p1_3[0].checked && !document.mainForm.p1_3[1].checked) alert("3 - some warning here"); else if(!document.mainForm.p1_4[0].checked && !document.mainForm.p1_4[1].checked) alert("4 - some warning here"); else if(!document.mainForm.p1_5[0].checked && !document.mainForm.p1_5[1].checked) alert("5 - some warning here"); else if(!document.mainForm.p1_6[0].checked && !document.mainForm.p1_6[1].checked) alert("6 - some warning here"); else if(document.mainForm.p1_7.value == "") alert("7 - some warning here"); // this condition does not work: else if(document.mainForm.p1_8.selectedIndex == 0) alert("8 - some warning here); // can't get the selectd field from the html select field else window.location = "OTHERPAGE.html"; } </code></pre> <p>that's pretty much what the function does, all conditions work except for that one i put the comments on. (i'm still learning so don't laugh at my code... please.)</p> <p><strong>Sorry i actually got this solved, there were some errors in the html code from my php array. Now it actually works. Thanks.</strong></p>
