How do I get values (into input fields) from the Basic example with values to save in the database?

When you add event listener on value.mdb.multiRangeSlider event, you can get array with values from event.values.rounded key on every slider change and next send it to database when needed. You can check working example snippet here (JS tab): https://mdbootstrap.com/snippets/standard/molborska/2855858

First, there is one minor error in your initialization of slider - please use startValues instead of start to precise an array of values.


new mdb.MultiRangeSlider(filteragerange, {
    min: agesldr.rangeminage,
    max: agesldr.rangemaxage,
    step: 1,
    tooltips: true,
    startValues: [agesldr.prefminage, agesldr.prefmaxage]
  });

Unfortunately, after investigating this issue we confirm, that there is a bug with displaying tooltip values. Thanks for your report and we will try to fix it as soon as possible.

I've also noticed that if you slide the last handle, it doesn't stop at the end. It jumps to the beginning.

The snippet did help, thank you. Info does get saved into my database. However, the value of the tooltip doesn't match the actual value.

I'm working on an age filter system, and I pull age preferences from the database / defined constants from a function.

var agesldr = {
  rangeminage: <?= $minage; ?>,
  rangemaxage: <?= $maxage; ?>,
  prefminage: <?= $sessfilterrow['filminage']; ?>,
  prefmaxage: <?= $sessfilterrow['filmaxage']; ?>
}

This is what renders for my current session:

var agesldr = {
  rangeminage: 18,
  rangemaxage: 125,
  prefminage: 44,
  prefmaxage: 125
}

My initialization:

<div class="slider" id="filteragerange" data-mdb-tooltip="true" data-mdb-step="1"></div>

new mdb.MultiRangeSlider(filteragerange, {
    min: agesldr.rangeminage,
    max: agesldr.rangemaxage,
    step: 1,
    tooltips: true,
    start: [agesldr.prefminage, agesldr.prefmaxage]
  });

The data-mdb-value (set at max) doesn't match the .textContent/.innerHTML value of the tooltip.
