m working on a component where a table is generated by data entered into 3 input fields (Year, Make and Model). I have a function where the user's inputs are assigned to their corresponding variable which are then to be added to an object type attribute, GarageItems. This would then be used to populate the datatable in my component. How could I do this?

 Here is my Component

<aura:component>

       <aura:handler name="init" value="{! this }" action="{! c.init }"/>

   
       <aura:attribute name="YearInput" type="Integer"/>
       <lightning:input aura:id="IdYear" name="CarYear" placeholder="Please type the Car's Year" value="{! v.YearInput }" />
           
       <aura:attribute name="MakeInput" type="String"/>
       <lightning:input aura:id="IdMake" name="CarMake" placeholder="Please type the Car's Make" value="{! v.MakeInput }" />
       
       <aura:attribute name="ModelInput" type="String"/>
       <lightning:input aura:id="IdModel" name="CarModel" placeholder="Please type the Car's Model" value="{! v.ModelInput }" />
   
   
       <aura:attribute name="GarageItems" type="Object"/>
       <aura:attribute name="Columns" type="List"/>

       
       <div style = "height: 300px">
           <lightning:datatable
                   key-field="id"
                   data="{!v.GarageItems}"
                   columns="{!v.Columns}">
           </lightning:datatable>
       </div>

   
   <lightning:button variant="brand" label="Submit" title="Submit action" onclick="{! c.SubmitData }" />
   <lightning:button variant="brand" label="Clear Fields" title="Clear action" onclick="{! c.ClearFields }" />

</aura:component>

Here is my Controller

({
    init: function (cmp, event, helper) 
        {
             cmp.set('v.Columns', 
                     [
                         {label: 'Year', fieldName: 'CarYear', type: 'integer'},
                         {label: 'Make', fieldName: 'CarMake', type: 'text'},
                         {label: 'Model', fieldName: 'CarModel', type: 'text'}
                     ]);
        },
    
    
    SubmitData : function(component, event, helper) 
        {
            var Year = component.get("v.YearInput"); 
            var Make = component.get("v.MakeInput"); 
            var Model = component.get("v.ModelInput"); 
            
            if ((Year != "")&&(Make != "")&&(Model != ""))
                
                {

//take year.make.model and add to GarageItems; **This is where I'm having the issue**

}
            
            else
            {
                return null;
            }
            
        },
    
     ClearFields : function(component, event, helper)
        {
            component.set("v.YearInput", "");
            component.set("v.MakeInput", "");
            component.set("v.ModelInput", "");
        }
    
    
})

 

I'm attempting to create a lightning component that displays a table that takes the input of 3 values (All of which are text fields) and adds them to said table.
I've seen examples online of components featuring tables populated with pre-existing data (such as https://sfdcmonkey.com/2017/02/20/custom-sorting-lightning-component/ or https://developer.salesforce.com/docs/component-library/bundle/lightning:datatable/example) but none with blank tables that are then populated with user-inputted data.
Are there any resources that someone could recommend? I'm very new and this is my first time interacting with aura components.

Hello!

I am making contact search page where the Results and Errors pageblocks render based on the value of their corresponding booleans:

• public boolean ResultsPresent
• public boolean ErrorsPresent

The problem is when I do this: 

<apex:pageBlock title="Results" rendered="{!ResultsPresent}"> 

or this

<apex:pageBlock title="Errors" id="ErrorSection" rendered="{!ErrorsPresent}">

I keep getting "Unknown Property" errors.

Here are the pageblocks in question:

<!-- Results Display -->
            <apex:pageBlock title="Results" rendered="{!ResultsPresent}"> 
                
                <apex:outputText value="There are currently '' results found." />

           return null;     
      }           
}

In a similar vein, I'm trying to also make an outputtext box that displays the number of results based  the value of MatchingContacts  but when I do that, I ALSO get an unknown property error. 

What am I missing here?

I'm working on a contact search page and I have a problem. My console has no errors but when I run a search, the results don't generate and all my input validation errors prompt.

For Example: 






Here is my VisualForce Page:
 

<apex:page id="ContactPage" controller="Ctrl_ContactSearch">
  
     
      <apex:tabPanel id="ContactPanel">

What do I have wrong here?

I'm making a contact search page. The search criteria are Name, Phone Number and Email. I'm trying to attempt the following logic.

• SearchContacts is pressed
• Checks for Blank Fields
• Validate input(Name,Phone,Email)
• Search Contacts for matches
• Generate Contact table with results

My current problem is that I have 3 Input Validation methods and not sure how to call their results into my "Search Contacts" function. Could someone provide me a solution on how to do this?


Here are the validation functions: 

/* Name Input Validation Regex*/
   public static Boolean ValidationName (String name)
            {
                Boolean NameIsValid = false;
                
              
                String nameRegex = '/^[a-zA-Z][a-zA-Z0-9]*(_[a-zA-Z0-9]+)*(__[cC])?$/';
                Pattern PatternName = Pattern.compile(nameRegex);
                Matcher nameMatcher = PatternName.matcher(name);
                
                if (!nameMatcher.matches()) 
                    
                NameIsValid = true;
                return NameIsValid; 
            }
    
     
    /* Phone Input Validation Regex*/
    public static Boolean ValidationPhone (String phone)
            {
                Boolean PhoneIsValid = false;
                
               
                String phoneRegex = '//^\\(?([0-9]{3})\\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$//';
                Pattern PatternPhone = Pattern.compile(phoneRegex);
                Matcher phoneMatcher = PatternPhone.matcher(phone);
                
                if (!phoneMatcher.matches()) 
                   
                PhoneIsValid = true;
                return PhoneIsValid;        
            }          
    
   
     /* Email Input Validation Regex*/
     public static Boolean ValidationEmail (String email)
            {
                Boolean EmailIsValid = false;
                
               
                String emailRegex = '/^\\w+([\\.-]?\\w+)*@\\w+([\\.-]?\\w+ (\\.\\w{2,3})+$//';
                Pattern PatternEmail = Pattern.compile(emailRegex);
                Matcher emailMatcher = PatternEmail.matcher(email);
                
                if (!emailMatcher.matches()) 
                    
                EmailIsValid = true;
                return EmailIsValid;    
            } 


And here is the method I want to call those results into: 
public PageReference searchContacts()
        {
                           
            
            
              /* Checks if input fields are empty*/
            if (name == '' || phone == '' || email == '')
                {
                    Error_FieldsEmpty = true;   
                    ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR,'One or more of your fields are blank. Please enter your information in the remainding fields to proceed'));
                }         
            else 
            {
                /* Check Validations*/
                
                
                
                
            }

Hello!

I am making contact search page where the Results and Errors pageblocks render based on the value of their corresponding booleans:

• public boolean ResultsPresent
• public boolean ErrorsPresent

The problem is when I do this: 

<apex:pageBlock title="Results" rendered="{!ResultsPresent}"> 

or this

<apex:pageBlock title="Errors" id="ErrorSection" rendered="{!ErrorsPresent}">

I keep getting "Unknown Property" errors.

Here are the pageblocks in question:

<!-- Results Display -->
            <apex:pageBlock title="Results" rendered="{!ResultsPresent}"> 
                
                <apex:outputText value="There are currently '' results found." />

                    <apex:pageBlockTable value="{!contacts}" var="c" id="contact-table">

In a similar vein, I'm trying to also make an outputtext box that displays the number of results based  the value of MatchingContacts  but when I do that, I ALSO get an unknown property error. 

What am I missing here?

I'm working on a contact search page and I have a problem. My console has no errors but when I run a search, the results don't generate and all my input validation errors prompt.

For Example: 






Here is my VisualForce Page:
 

<apex:page id="ContactPage" controller="Ctrl_ContactSearch">

What do I have wrong here?

I'm making a contact search page. The search criteria are Name, Phone Number and Email. I'm trying to attempt the following logic.

• SearchContacts is pressed
• Checks for Blank Fields
• Validate input(Name,Phone,Email)
• Search Contacts for matches
• Generate Contact table with results

My current problem is that I have 3 Input Validation methods and not sure how to call their results into my "Search Contacts" function. Could someone provide me a solution on how to do this?


Here are the validation functions: 

/* Name Input Validation Regex*/
   public static Boolean ValidationName (String name)
            {
                Boolean NameIsValid = false;
                
              
                String nameRegex = '/^[a-zA-Z][a-zA-Z0-9]*(_[a-zA-Z0-9]+)*(__[cC])?$/';
                Pattern PatternName = Pattern.compile(nameRegex);
                Matcher nameMatcher = PatternName.matcher(name);
                
                if (!nameMatcher.matches()) 
                    
                NameIsValid = true;
                return NameIsValid; 
            }
    
     
    /* Phone Input Validation Regex*/
    public static Boolean ValidationPhone (String phone)
            {
                Boolean PhoneIsValid = false;
                
               
                String phoneRegex = '//^\\(?([0-9]{3})\\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$//';
                Pattern PatternPhone = Pattern.compile(phoneRegex);
                Matcher phoneMatcher = PatternPhone.matcher(phone);
                
                if (!phoneMatcher.matches()) 
                   
                PhoneIsValid = true;
                return PhoneIsValid;        
            }          
    
   
     /* Email Input Validation Regex*/
     public static Boolean ValidationEmail (String email)
            {
                Boolean EmailIsValid = false;
                
               
                String emailRegex = '/^\\w+([\\.-]?\\w+)*@\\w+([\\.-]?\\w+ (\\.\\w{2,3})+$//';
                Pattern PatternEmail = Pattern.compile(emailRegex);
                Matcher emailMatcher = PatternEmail.matcher(email);
                
                if (!emailMatcher.matches()) 
                    
                EmailIsValid = true;
                return EmailIsValid;    
            } 


And here is the method I want to call those results into: 
public PageReference searchContacts()
        {
                           
            
            
              /* Checks if input fields are empty*/
            if (name == '' || phone == '' || email == '')
                {
                    Error_FieldsEmpty = true;   
                    ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR,'One or more of your fields are blank. Please enter your information in the remainding fields to proceed'));
                }         
            else 
            {
                /* Check Validations*/
                
                
                
                
            }
