xProteuSx Posted January 25, 2012 Share Posted January 25, 2012 I have created a table with a series of checkboxes. At the bottom of the table there are 'Check All' and 'Uncheck All' buttons. For some reason, some of the boxes get checked, while some don't, and I can't figure out, for the life of me, why the ones that don't get checked aren't getting checked! Its driving me crazy! I know that this is an unformatted mess, but copy and paste it into a .html file, and see the problem for yourself (PLEASE!): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

xProteuSx Posted January 25, 2012 Author Share Posted January 25, 2012 I just realized that neither the Check All or Uncheck All buttons work if the array, as in 'cmarked4[], only has one index. The array must have at least two indexes, or else these buttons don't work. How do I get around this?

xProteuSx Posted January 25, 2012 Author Share Posted January 25, 2012 Figured it out ... Changed this: if (document.markform['cmarked4[]']) { for (i = 0; i < document.markform['cmarked4[]'].length; i++) {document.markform['cmarked4[]'].checked = true ;} } To this: if (document.markform['cmarked4[]']) { if (document.markform['cmarked4[]'].length > 0) { for (i = 0; i < document.markform['cmarked4[]'].length; i++) {document.markform['cmarked4[]'].checked = true ;} } else {document.markform['cmarked4[]'].checked = true ;} } Link to comment https://forums.phpfreaks.com/topic/255734-check-all-button-for-checkboxes/#findComment-1310965 Share on other sites More sharing options...
UrbanDweller Posted January 25, 2012 Share Posted January 25, 2012 Hey, Are you just wanting to check and deselect ALL of your checkboxes in the form or per day only?
