Create Multiple Records of Salesforce Objects from a Single Page
Presently we can create records by click on tabs of their related objects but through the below-given piece of code, we can create records of any object in the org either a standard or a custom object from a single Visualforce page only. Follow the below code to achieve the task.
Let's have a piece of code that you need to save to your org for achieving this.
Visualforce Page Code:
<apex:page controller="FieldSelectSobjectTypeClass">
<apex:form id="od">
<apex:pageblock>
<apex:pagemessages rendered="true"></apex:pagemessages>
<apex:pageblocksection>
<apex:pageblocksectionitem>
<apex:outputlabel value="Object List"></apex:outputlabel>
<apex:selectlist size="1" value="{!selectedObj}">
<apex:selectoptions value="{!objects}"></apex:selectoptions>
<apex:actionsupport event="onchange" action="{!details}" rerender="od"></apex:actionsupport> <!-- for selecting any other object in picklist-->
</apex:selectlist>
</apex:pageblocksectionitem>
<apex:pageblocksectionitem>
<apex:panelgrid columns="3">
<apex:panelgroup style="width: 40%;">
<b>Available Fields</b>
<apex:selectlist value="{!sfields}" multiselect="true" style="width: 120px; height: 120px;">
<apex:selectoptions value="{!fsnOption}"></apex:selectoptions>
</apex:selectlist>
</apex:panelgroup>
<apex:panelgroup style="width: 20%; height: 120px;">
<table height="120px">
<tbody>
<tr>
<td> <apex:commandbutton value="Add" action="{!addFields}" style="width: 80px;" rerender="od"></apex:commandbutton></td>
</tr>
<tr>
<td> <apex:commandbutton value="Remove" action="{!removeFields}" style="width: 80px;" rerender="od"></apex:commandbutton></td>
</tr>
</tbody>
</table>
</apex:panelgroup>
<apex:panelgroup>
<b>Selected Fields</b>
<apex:selectlist value="{!rfields}" multiselect="true" style="width: 120px; height: 120px;">
<apex:selectoptions value="{!fsOption}"></apex:selectoptions>
</apex:selectlist>
</apex:panelgroup>
</apex:panelgrid>
</apex:pageblocksectionitem>
<apex:commandbutton value="Click Here" action="{!queryMydata}" rerender="od"></apex:commandbutton>
<apex:pageblocksectionitem rendered="{!pbtflag}">
<apex:pageblocksection>
<apex:repeat value="{!listWrapper}" var="f">
<apex:repeat value="{!f.fields}" var="l">
<apex:inputfield value="{!f.sObj[l]}"></apex:inputfield>
</apex:repeat>
</apex:repeat>
</apex:pageblocksection>
</apex:pageblocksectionitem>
